    I have no problems with connecting from an RV042 behind NAT to WRV200, thanks to the WRV200 NAT-Traversal function. But, somehow, I'm unable to do the same when trying to connect to another RV042.

    What particular tunnel settings I should try? Especialy, what security group settings should I use?

    I was able to make the tunnel connect using the "Dynamic IP + Domain Name(FQDN) Autenthication" function for the NAT-ed router. Unfortunatelly, the connection does not seem to be working as it should to.

    When tried to do the same on another Internet line without NAT, everything was working correctly. So the tunnel settings seem to be correct. The problem is somehow related to the NAT without the IPSec passthrough, probably.

    Loading the firmware to both routers fixed the problem. Apparently the firmware is buggy when it comes to the NAT traversal.
