And your Solaris system needs to nat and route traffic to this virtual network. Exactly. I'm not sure if Solaris supports that or not, but perhaps someone else knows. I haven't played with Solaris in 10 years, so I'm way too rusty to say anything more specific here. If I had plenty of time, and a Solaris machine to experiment on, I might be able to do this, but time and a machine to crash is not something I have around here. :-) It's changed a bit in the last 10 years as well. :-D But in theory, it's not that tricky. You need to know how to do NAT under Solaris, and you need to know how to set up a virtual network (be that with some external program, or if Solaris can bridge interfaces together). Yeah, which is what I'm attempting to do. I've got two TAP interfaces bridged together. One SIMH talkes to, the other Solaris has an IP on. Can't ping back and forth, however. :( -brian -- "Coding in C is like sending a 3 year old to do groceries.
