Hmm. I've not seen the local gateway stuff before. I've always seen it 
be something like

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
127.0.0.0       0.0.0.0         255.255.255.255 UH    0      0        0 lo
192.168.2.0     0.0.0.0         255.255.255.0   U     0      0        0 eth1
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
0.0.0.0         192.168.1.251   0.0.0.0         UG    0      0        0 eth0

I don't know if that's the problem, though...

A couple other odd jabs:

* I take it that a traceroute from your laptop to 192.168.1.x will 
  stop at 1.251, right?

* I take it you've done all the right /proc twiddling to allow your 
  fileserver to forward IP packets, i.e.,

  sysctl -w net.ipv4.ip_forward = 1
