Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

there is no need for a gateway since both hosts are connected via cross cable.

Either your mask or broadcast on both eth1 is wrong, this pair does not match:
I suppose your mask should be 255.255.255.0!

your suspect nmblookup problem should be solved by editing your appropiate smb.conf
