I'm currently trying to get BTMM running correctly on my PowerPC Macbook running 10.5.5, using a DSL modem with an Airport Extreme v5.7 w/ 802.11g.

When NAT is Enabled on the Airport, i click Start in BTMM and get the following error...

back to my mac is not working properly because you may have more than one device on your network providing network address translation (nat). try disabling nat on one of the devices.

When NAT is Disabled on the Airport, i click Start in BTMM and get the following error message for a split second, then it reverts back to the above error message immediatly...

back to my mac is not working properly because it requires a router that supports NAT Port Mapping Protocol NAT-PMP or Universal plug & play UPnP. make sure your router supports one of these protocols and that it is enabled.

CAN SOMEONE PLEASE HELP ME WITH THIS???
