So I installed slackware 8.1 last weekend and everything else works fine, exept the internet. So I have lan connection to switch there is ISDN connection to company where is my nameserver and proxy server (not on same server). All configs are set (netconfig and resolv.conf) but I can't connect to Internet. I can how ever connect to my company and from companys homepage I can surf the web using links, but at the moment I touch the address bar connection fails. It seems that problem is proxy, but all proxy settings have been set correctly. Can anyone help me here?

Thanks for all who have even read this far.

try running ping like
"ping x.x.x.x"

where x.x.x.x is the default gateway they gave you, then try to ping the proxy server and then try to ping company's homepage, then you can see where the problem is.
