I JUST setup a router in Mandrake ... so here's a quick question for you. How have you tested to see if it the system behind your firewall can make it to the internet? Web browser? If so, try using an IP instead of a dns name. (ex. instead of http://www.google.com try http://216.239.35.100)
If this works then it's just a DNS issue, which is easily fixable. Only reason I bring this up is because I just had the same problem, did this and it worked. -- ************************************************************************ * Jon "GenKiller" Gaudette ultra übergeek * * Webmaster / Founder -|- DDN -|- http://www.digital-drip.com * * Co-Webmaster -|- CNCNZ -|- http://www.cncnz.com * * Co-Webmaster -|- APS -|- http://auburn.k12.ma.us * ************************************************************************ David Busby wrote: >List, > I'm new to Linux (very new (3 weeks)) and am trying to migrate my >office network from Microsoft to Linux technologies.
