Using FQDN instead of IP

[kooma]

I've got my PIX to route telnet in and out. Instead of connecting with an IP, I want to use the DNS that is registered to the IP on the internet.

If I use XXX.domain.com it does not connect. If I ping it I get the translation to the right IP but it does not reply.

If I use the IP, it connects no problem..

Can someone help?


Thanks!
