Hi Simon, > NAT Traversal Strategies (require help from NAT box or external helper) > Port forward supported proxy. In most cases, proxy is not required. I have a system running ProxyForNAT=0, with ATA-186, Cisco 827, and Planet VIP-400 EPs behind dumb NATs, using only port forwarding. UPnP, STUN, or gnugk awareness is not required. Incoming and outgoing both work fine, including calls from one NATed EP to another. This works because an EP sends its private address and RPT port in OLC/OLCack, which gnugk replaces with the public IP when it sends it to the other EP. The port number is unchanged, so the RTP packets go to the NAT box, on the right port to be properly forwarded to the EP. The only problem with this scheme is that ProxyForNAT is a global setting. It would be nice if it could be enabled on a per-endpoint basis, so that proxy would still be available if a few endpoints really need it. --Stewart ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
