Hi - First, apologies if this sounds familiar.  I posted this earlier and the thread died out without resolution.  I still have the problem so I am restarting fresh.  I had a lot of good advice from prisaz that probably has advanced my cause but I haven't achieved port forwarding success yet.


I have the Actiontec router bridged to a SMC Barricade Router that serves my wired home network. 


One computer ( a laptop) has a wireless card - the rest of the home network is wired via the SMC router.



I cannot port forward to any computer that is connected to the SMC.  I want the Actiontec to forward to the SMC router which in turn will forward to the specific networked machine.  But I cannot get the Actiontec to resolve the network address of the SMC.


Due to previous suggestions I did the following:


  changed  the DHCP distribution range on the Actiontec to -


 In the SMC changed the WAN address to static and assigned it and the Gateway and DNS as


Set the Actiontec to forward to address


But port forwarding is not working and it is driving me crazy.



 Port Forwarding setup in Actiontec (I have tried every combo I can think of but this is the obvious first try - that does not work):


Specify Address 

Protocol  tcp 

Rule Name Blah

Ports TCP Any -> 1333

I know this is a lot to digest.  I have tried to present all the relevant details.  Is there something I am doing wrong?  Thanks, Jim Gallagher

The following is the reply I received from Actiontec - I add it here as a public service in case some other person has a similar issue.


The Actiontec shouldn't even be used in your situation. Your SMC should be
connected directly to your modem. I would suggest one of two options.
ONE: DMZ Host the WAN IP of the SMC unit. This would by pass the firewall
in the MI424. The unit cannot be bridged and made transparent to act as a
switch, there is no programming for that.
TWO: Contact Verizon to change the data connection so your SMC unit can be
directly connected to the modem.
Trying to port forward from one router firewall to another is almost
impossible. You can try, but its doubtful it will remain consistent.
To forward ports in the MI424 you would forward the ports using these
instructions to the IP of the WAN of the SMC.
In the SMC you would then port forward to the computers IP received from
the SMC unit.


There was more to the response but the rest was just step by step of how to set the port forward settings.

PS - my solution was to remove the SMC router and replace it with a switch.  The only reason I wanted to keep the SMC attached in the first place was because it conveinantly has a printer attachment built in. After moving to a switch I had to attach the printer to a networked computer and re-do the printer sharing settings.
