I bet it changed your FQDN for the box - For example it went from
yourmom.belkin.com to yourmom.somethingelse.com - Some routers pull the DNS
suffix from their WAN router and some don't. If your FQDN changed, the
frontend may be doing some weird DNS query and freaking out. Run a reverse
dns query (fire up nslookup, plop in the IP address and see what name it
spits at you), and see if it matches the name you get when typing hostname
on the backend.
