I still have problems with my ISDN's connections :(

Hi all.

OK, my ISDN setup is still not working, it becoming a real pain. When I ftp I get this error in the logs....

*Mar 1 01:55:03.335: IP: NAT enab = 1 trans = 0 flags = 80

As you can see, encapsulation fails, this connection should use NAT, but I dont see (thie was debug all) NAT doing anything at all.... Here is my configuration (Both Dialer1 & Dialer2 fail to work, Dialer 2 does not use NAT)

Anybody got any idea?? is NAT setup OK??? What does &quot;map-class dialer DialClass&quot; do???? Should I shoot myself, or would drowning be better?????

you must use ip nat pool interface bri0 or dialer overload

you have not defined what inside source addresses NAT should translate. Take a look at this link:
