Sure you can. Just add an additional instance of TCP/IP in the control panel
and give it another IP address. The Original 95 did leak memory when doing
this though (I think it is now fixed).

Since they are on a 192.168.X.X net you would need to use NAT to translate the
addresses or give each box two IPs. The OR-U will not support NAT or sub
interfaces until the 3.9 release. However if you run the 3.9 open beta on the
PM3 you can do server side NAT for the OR-U dialing into it. The other Option
is to route the 192.168 net to your network internally and setup a proxy for
them to point to.
