Port Forwarding Verizon?

© February 2008 Anonymous

While browsing for info on a connection problem I have, I ran across your writeup at Verizon FIOS

Until last weekend, I had Verizon's FiOS with 5/2 internet service for over a year and quite pleased with it. While there have been a few times when response time has been slow, it has been consistently better than the Broadband Cable Modem service I previously had through Adelphia (which got bought out by Time-Warner) ever was.

A week and a half a go, I called Verizon to sign up for FiOS TV. That was installed last Saturday. In the process of installing it, they replaced the D-Link router they had provided for the 5/2 internet service with an Verizon router which has a sticker on the bottom of it indicating it's an Actiontec MI424-WR. It now has 15/2 internet service.

During installation, I was puzzled by the fact that a coax cable was run to the router. On questioning the installer, he indicated the TV menu info is stored in the memory of the router and the set-top boxes access it over the coax line. He also indicated the higher speed 15/2 service is needed to support the TV functionality.

I'm quite pleased with the fact the image quality off of the high-def DVR is significantly better than I was getting from the high-def DVR I had from Time-Warner. My daughter watches it a lot more than I do and indicated the image quality we're now getting from the low-def is about the same as the hi-def we had from Time-Warner and the hi-def from the FiOS is even better.

On the down side, there are significantly fewer channels available for a TV that doesn't have a set-top box. But, from what I hear, every TV is going to need to have a set-top box in the near future. Thanks to a law passed by Congress and signed by President Bush a few years ago, the FCC is recalling all of the current analog channel frequencies so that they can be allocated to different usages such as public safety. The new law basically says all analog broadcasts must be replaced by digital broadcasts no later than February 2009.

For any TV with a set-top box, I'm now only out one channel (KEYT) that we watched fairly regularly for local news. It's kind of a bummer since KEYT (about 50 miles north west of here) has better local news coverage than the LA stations 50 miles south west of here do. The Los Angeles area has enough of their own local news to supersede news from surrounding counties meaning only the really "hot" local news items air on any of the LA stations.

Bottom line is that I'm quite pleased with the image quality improvements and willing to give up the one channel for it. I haven't received my first bill on FiOS TV yet but bottom line price is supposed to be quite similar to what I had before the switch.

The one and only issue I don't have resolved yet (and reason for my internet search) is configuring the Verizon (Actontec) router to forward port 9100 to my laser printer so that when I'm at home and logged into a computer a work, I can print on my home printer without having to scp the file to my home system for it to invoke the print. I thought I had that working last weekend.

I lost A/C power during the week due to a storm. I've since updated /etc/hosts on computers at work to reflect the IP address my Verizon router is now using but still haven't been able to get a print to come out on the HP LaserJet 1320n I have at home.

I've also reviewed the port forwarding on the Verizon router and it seems correct also.

Any ideas on what I might be overlooking?

My first thought is the router lacking a proper gateway - if it can't ack packets it can't print.

If that's not it, I wonder if the Actiontec won't pass to addresses it didn't assign by DHCP. I think that router can reserve IP's by MAC address, so programming it with the IP desired on the printer might change things.

I just double checked the printers settings and it seems fine to me. It has as the default gateway.

The printer was working previously before the D-Link router was replaced by the Verizon router. I have set the IP address of the Verizon router's local net to which is what the D-Link had been using. The printer is currently

I had to change from using 192.168.1.x addresses to 192.168.100.x when I first started working for my present employer. Without that change, I could not establish a VPN connection to network at work. There the local side of the network is using 192.168.1.x addresses.

It might be related to the DHCP settings of the router. The last changes I made to the router were to its DHCP configuration to eliminate an IP address conflict I was having between my daughter's laptop and my hard wired desktop that has a static address.

I just got this working after talking to a support person at Actontec.

So, procedure to setup port-forwarding on an Actiontech MI424-WR is as follows:

1) Select Firewall Settings 2) Click "Yes" box to proceed 3) select Port forwarding from left hand menu 4) scroll to bottom and click "add" 5) Under "Networked Computer/Device" leave "Specify Address" selected and enter the static IP address of your printer in box to the right of it. 6) click under "Protocol" section, click the "Add" 7) On Edit Service window, click "Add Server Ports" 8) On Edit Service Server Ports" window, set "Protocol" to be TCP, leave "Source Ports" set to "Any" and set "Destination Ports" to be Single with port number 9100 9) Click Apply boxes until you're back to the router's main menu

That sounds normal.. what did you have before?

I had mistaken the meaning of the "Source Ports" setting.

When I initially set it up, I was thinking about config on the Fortigate-50 where you can route an connection to a given port to a different port on the target device it's forwarded to and made the assumption that the Actiontec worked in the same manner.

In other words, I had set it to single port of 9100 thinking that I was saying if something tries to connect to port 9100 on the router then route it to port 9100 on the printer.

But, in actuality, I told it to only accept input if it originated from port 9100 on the remote computer trying to print.

Ah, yes: routers do often mean different things there..

So I discovered. It didn't help not having a decent write-up in the manual that came on CD. That talked about how you can select one of their canned port definitions for a tons of games but no description of what each of the different settings meant if you had to roll your own for anything else.

From web searching for answers, I found many others were having same issue trying to configure it with no meaningful response from anyone who replied to them which lead me to believe the solution was more complex and result of some type of conflict.

I was going crazy trying to figure out why ActionTek uses THREE variables when just about every other router uses TWO.
From the internet- I come in on port A
When the router sees a requrest on port A, it should route it to the local net IP address specified:port B

Why ActionTek needs to specify a port C, I do not understand.

If you've never seen the menus:

Incoming port:
Source Port
Destination Port

Outgoing port:
Specific or same as incoming.

Why would you need source and destination port fields to specify the source port?

I can see if you want to specify a range, but geeze- grey out some options if you only need one port!

While trying to deal with the same port forwarding issue, I decided on a different approach that seems to be working quite well - though time will tell. Basically, I simply set the Actiontec up as factory default, and DMZ'd my original router, a Netgear. I also turned off the wireless network on the Acttiontec. The Netgear gets its IP from the Actiontec's DHCP server, and is the only device connected to it. Since it's DMZ'd, all traffic goes through 'naked' to the Netgear, which then becomes the internet 'front end' as it was before. This way, the Actiontec still delivers its services to the Motorola cable box, but leaves the computer decisions to the Netgear. So far, all seems to work OK.

Yes, I have done similar setups in the past.. such a waste, but as you have to use their router if you have FIOS TV, you are stuck.

"I had mistaken the meaning of the "Source Ports" setting."
Thanks for this, found in google search, and now my port forward works!

So what did you find out the "source port" mean?

As explained above, it depends on context and what the specific vendor means by it.
