[Serusers] nat problem maybe?

folks, i think i am having a nat problem. my client is timing out while trying to contact the ser server. i am using stun which appears to be working ok. i am including the output from my kphone client as well as the ser server, hoping someone on the lilst can help me decipher what is going on here. i dont know if the "No Route headers found" is the problem or what... tia, daryl kphone client: % kphone Found 2 interfaces.
