Working network connectivity, not working DNS resolutions



Hello debian-users,

I have run into an interesting issue with the DNS resolution on only one of my debian lenny systems on my network.

I have confirmed that this system has working network connectivity but I would like to restore the ability to query DNS records from my local DNS server which is also in my case my network gateway. Additionally I can ssh into the system easily while connected to the same local network 10.254.2.0/24

The working (as in with other systems on my network) DNS and router is at 10.254.2.254/24. The IP statically set for the debian system is 10.254.2.1/24

Some info from this AMD64 architecture system is below.

root@localhost:~# cat /etc/debian_version
5.0.4


root@localhost:~# cat /etc/resolv.conf
domain site
search site
nameserver 10.254.2.254


root@localhost:~# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.254.2.0      *               255.255.255.0   U     0      0        0 br200
default         10.254.2.254    0.0.0.0         UG    0      0        0 br200


Snippet from /etc/network/interfaces:

# LAN bridge

 broadcast 10.254.2.255
 gateway 10.254.2.254
 bridge-ports eth1.200

Advice on how to troubleshoot further would be much appreciated, thanks.
