Cant establish SMTP or HTTP connection through Linux firewall

Asked by vizient in IP Tables/IP Chains, Linux Networking, Linux Network Security

Tags: , ,

Hello,

Ive got an Ubuntu Linux VM setup as our firewall/router for our DSL connection. The DSL modem is currently in transparent bridge mode (Qwest 2wire modem) so PPPoE is done in Linux. Im using the Firestarter GUI to configure iptables. All is well except for the incoming connections, only ports 80 and 25, arent being established to the server that I specified in the firewall policy. Any ideas?Start Free Trial
