troubleshooting a connectivity problem
Posted on 2005-04-14
I'd like some help troubleshooting a Internet connectivity problem. The situation is an internal lan client
with a gateway firewall (mandrake OS and iptables) with an internal and external interfaces.
Am unable to get out to the Internet from the lan, but can get out locally from the firewall.
I'd really like some tips on network troubleshooting tips. The problem arose after a house move. All else stayed the same
except the network scripts weren't saved. The firewall hasn't changed,except its running over ppoe now.
I'm not looking for a solution just loads of tips on how to investigate this.
