Nat issue with Opt1

360andy · May 23, 2007, 5:49 PM

I have Comcast cable with 5 statics (Wan), Eschelon t-1 with 5 statics (Opt1) and both are in bridge mode.

I have been able to access an internal server when I Nat using a WAN static IP and when I use ipchicken.com it shows the WAN address, which is as expected.

I need to access the internal server using a OPT1 static IP. I have load balancing setup and I have tried port forwarding and 1-1 using a static ip from OPT1 no luck. It seems as though I am missing a step.

Any help would be appreciated.

thanks

Andy

This should be fairly straightforward to setup. One thing to check is to make sure you added the Virtual Ips on the correct (OPT1) interface. With Dual-WAN, I would use port-forwards instead of 1-1 NAT- you cannot create a 1-1 to a particular IP on both interfaces.
PS- I just noticed you said your WANs are in bridge mode. Do you mean that your cable modem is acting as a bridge or you have an interface bridged to another?

Thanks DotDash.

The problem appears to have been that when I created my virtual ip's I used WAN instead of OPT1. It works great now.

Thanks again for your quick response.
