Hi, topic got a bit long ;). I'm running SuSEfirewall2 version 1.0 and have the problem that i can not reach services on the firewall through the external interface(ppp0). This is not a real problem, except that I run oracle on this machine an it seems like the oracle listener binds the connection to the external ip. This leads the firewall to filter any following packages and the connection times out :(. If anyone has a solution how to tell oracle to use only a specific interface, or how to tell SuSEfirewall to not filter packets from the internal net to the external interface - please let me know ;) Regards Christoph ps: I know it's not a good idea to run oracle on a firewall but it's only for testing purposes
