I have a couple of 760 series ISDN routers here, one of which does exactly what I want. The other, try as I might, I can not get working properly.
Although I can dial in, authenticate, and am assigned an IP address (IPCP) I'm unable to reach the remote network over TCP/IP (using unnumbered routing as per the docs). I've played with both IP routing and PAT options but to no avail. TCP connections simply hang after the SYN is sent as there's no reply from the other end. I've snooped around the configuration and everything seems to be identical, although there must be an elusive difference lurking somewhere. I've also tried a completely separate router, starting from the default configuration after a full reset.
Does this ring any bells? If not, is there a way to dump the configurations of both routers (e.g. to a file) so I can compare them more easily? I've checked the manual and command reference but found nothing of use.
Many thanks in advance,
