Linksys RV042 VPN connection to a Cisco 1720 behind a firewall

I am attempting to set up a remote site connection to my main site using a RV042 to a Cisco 1720 and am recvieving the following in the logs:

We require peer to have ID '65.43.191.251', but peer declares '192.168.0.1'

Are you seeing this on the RV042?

What kind of firewall do you have in front of the 1720? Is that firewall's IP actually 65.43.191.251 and you are trying to NAT it to the 1720 at 192.168.0.1 ?

Yes, I am seeing this on the RV042, in the log file.  The 1720 is behind a PIX 515E.  The 65.43.191.251 is the public IP of the 1720 (one-to-one NAT).  192.168.0.1 is the private IP of the 1720.

The 1720 currently has several other site connected to it using other router models.  So, I know the 1720 is configured properly.  As a matter of fact, the RV042 replaced another router that was connected to 1720.

Have you enabled NAT-transparency on the PIX?

I did not, but I do now.  However, it does not make a diff.

Have you made any progress? Any changes to the situation?
Unfortunately, I don't have a RV042 to test the configuration with..

Unfortunately, no.  At this point, because of our continued growth and the absolute lack of the help from Linksys, I am going to start swapping Linksys router for Cisco 501s.

Thanks for your suggestions.

Good call. I was hoping that Linksys tech support would improve after Cisco bouth them, but I guess that won't happen anytime soon..

Good luck!
