This question may sbe much simpler than I am explaining it so please excuse me if it is confusing...

 

I have 10 static IP's from Comcast, using thier modem and a Netgear dual WAN firewall (FVS336GV2) thier modem is bridged.

 

Everything is working fine. Right now I have a couple devices- server, cameras, etc... and I have dual NIC cards in each. One for a static from the provier and one for a local WAN address.

 

My question is- how would I (if possible) route a specific static IP to in turn go to the internal WAN address to elminate the direct connection to the static Ip and just route it to a local.

 

Thanks in advance!

I'm not sure what you are trying to do. So I am a little confused.

 

what are you calling local WAN?

Sorry I meant LAN not WAN....

 

What I am trying to do is :

 

Comcast static x.x.x.56 <---- SEND TO-----> 192.168.x.a

Comcast static x.x.x.57 <---- SEND TO-----> 192.168.x.b

 

and so on.....

lol ok....I thought so but wanted to make sure =)

 

That is what a router does. I don't know your setup or why you need 10 static IPs but your little diagram is NAT(network address translation)

Typically, on the home/soho gear, you use firewall rules to do this.

With any luck you have a page that looks like this in your firewall rules.

 

You set the internal IP to the designated device, then change the NAT IP from WAN Interface to Single Address. From there, type in the desired external address, save it, and everything should work.

 

Now, on my SRXN 3205, I have found that this only works on INBOUND rules. If you do this, and need to use secure protocols, you will have trouble, as the outbound traffic will still be sent over the WAN Interface IP address... at least, if it works the same way mine does.
