Hi all a couple of weeks ago I was working on the problem to set up a linux box (rh9a) as a router. ( I am still working on it as I have time available) thinkpad (wireless) -> rh9a (router) -> clark box -> isdn router -> internet http works fine from and to the thinkpad and a wireless Palm Tungsten C. But I can not access my mail servers. I did enable ipv4 forwarding in /etc/sysctl.conf Iptables are ok. all is forwarded. what else could cause a problem that the dns can not be resolved or the pop / mail server can not be accessed? Thank you very much in advance. Ben -- Shrike-list mailing list Shrike-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/shrike-list
