Windows 2008 RRAS - Port mapping to 127.0.0.1 doesn't work

-

hi,

i have windows 2008 standard (not r2) installed rras nat purposes. have 2 network adapters, 1 external ip dedicated (wan) and lan, purely used virtual network switch protocol hyper-v purposes (created virtual network manager). there's lan interface created virtual network manager (192.168.0.1).

i have rras set between wan , lan. it's , working fine.

i'm trying port mapping working loopback interface. have service running @ tcp 127.0.0.1:25 (can connect telnet server).

i've tried first rras gui smtp rule forwarding external 25 port 127.0.0.1:25. no success (can't telnet outside). approach done netsh routing ip nat add portmapping name=wan proto=tcp publicip=0.0.0.0 publicport=25 privateip=127.0.0.1 privateport=25 with same no luck result.

if change this port forwarding lan 192.168.0.1:25, it's working fine. can connect outside. thing want differ these ports - 127.0.0.1 external connections , 192.168.0.1 internal.

i had done before windows 2003 r2 server, migrated 2008 , there's problem arised.

any ideas?

hi,

i think there kind of service cofiguration issue, because other services (like iis) available outside being located @ 127.0.0.1:25. have changed service config not use loopback interface.
