Been working this for over a month now and I'm stumped. Everything was working until the 'crash'. Backup was no good so I did a fresh install of centos 5.5. Trying to get things back like they were but its been a really long time since I had to set things up from scratch, Redhat 2.0. My centos server acts as a gateway/firewall/router for my home network. Internal machines can access the internet. The server can access the internet. I can access my server/services from outside the local network but internal machines cannot. Any ideas/suggestions? Thanks, --Eddie
