[nflug] Verizon dsl

I have a linksys router and had to use the dsl modem as a bridge so that I could network all my systems. This has to be done becuase the nat for the dsl modem shares the same network as the linksys router. I can't seem to find the link I used to set this up but I had to change the router to PPOE and set the dsl modem to be used as a bridge. I will try to dig the link up for the destructions and post it when I do.

I will second the dns notion! Verizon's dsl dns servers are really bad.
One other thing I can't stand about dsl, actually adsl, is there dhcp!
It is ridiculous, I've seen the IP's change by the hour! Actually been
bumped offline while ssh'd into some boxes because the freakin IP
changed. I never looked into it too much but they must have their dhcp
servers set to expire on the hour. If it wasnt for the bad dns servers
and the hyper dhcp settings, dsl is great, the service itself is
extremely reliable and fast.
