I'm fumbling around a bit for a solution to be honest. It does appear to
be a name resolution issue though, so running your own nameserver (DNS
server) would be a good start.

You can do it this way:
# yum install caching-nameserver
# chkconfig named on
# service named start

You should then edit /etc/resolv.conf and add the following line above
any other "nameserver" entries:

nameserver 127.0.0.1

See if that helps.

Note: this may have issues if your office LAN uses its own local DNS
domain; you won't be able to resolve names in that domain from the
router. I'm also assuming that your router is statically configured,
i.e. does not use DHCP. If it did, the /etc/resolv.conf file could get
clobbered by the DHCP client.
