Guys,
Not sure what is going on with my new openSUSE 11.2 install, but I am unable to use my server any more as a router. I have checked and ip_forward is on, but not of my boxes are able to get out. I have searched the opensuse forms and I see that I have all the settings that everyone recommends but still no access.
You will have to describe your configuration with some detail: crystal balls are quite unreliable nowdays. AFAIK, you only need to change a few things in the susefirewall file, it is really easy.
Is these two things really that bad in 11.2?
Not to my knowledge.
Chuck,
Yes, please describe your setup. ASCII drawings work fine. I don't know about 11.2, but from 11.0 on, I have been unable to get IP forwarding to work with the old "dial-in-server" config, using ppp to handle 'inbound' modem connections to act as your own 'dial-up' server. Up to 10.2, 10.3 worked fine. 11.0 on, ppp no longer talked tcp over the routes for some reason.
Not saying that is your problem, but maybe it figures into what you are doing. We'll know when we get your setup.

Ok, I will try to make this painless for everyone. I have two nic in my box. Since SuSE 5.3 to openSUSE 11.1 I have this set up wher eth0 is extranal and eth1 is internal. eth0 is the default gw. I have dhcp running and given out ip on eth1, with eth1 as the default ip for dhcp. I have check, and the ip forware is checked on the router tab. Below are the network config. I have a backup of my 11.1 /etc dir and I have checked and most of the same settings, expect I had to turn off ipv6, because the :::1 (localhost) was killing postfix. By the way, I am not running the firewall until I can figure this out, so I have no iptables rules loaded. Below are my config files...if there something else I need to post let me know. By the way, Samba is working which is cool.
