Now my desktop is connected to both networks and has "ipgate on" Its IP's are

Now the odd part. If I do something that requires file & print, for example a
directory list on a shared drive, it uses the 81 net - and it works. Now the
wired 81 net will get initialised first on an 81 address at boot. Then XWLan
comes along reassigns the NIC to 192.168.200.250 and inits the wifif card.
*Then* I login to the LAN which gets the shares going. I can't see either why
it does what it is doing, nor, more importantly, *why* it actually works.
Hi, Dave. You don't mention what IP is assigned to your desktop or which machine on your network is located at 192.168.0.4. It's probably something else on your LAN which is routing the traffic. As all 192.168.0.0 traffic should be routed through lan1 at 192.168.0.49 (including the 192.168.200.0 traffic), this is probably where your packets are flowing, getting bounced that direction from the IP bound to the Wi-Fi NIC.
Lewis, I did give the IPs and netmasks at the top of the post. 192.168.0.4 is a
Sparc which also has nics on both networks. The access point is on the 192
network so normally any traffic from that net that wants to go elsewhere would
go through the Sparc.
Oops...so you did! My apologies... I also had a feeling it was your Sparc. :-)
However, in the case I mention the *only* lights on the 81 net switch that are
blinking are the desktop and the laptop. If it were going via the Sparc I would
see three blinking.
Yes, you surely would. This is indeed quite odd, now isn't it? When I have a bit more time, I'll lay this all out in diagram form and see if I can figure out the trace. Speaking of which... Do you get any odd results when trying to run a traceroute on the traffic?
