Scenario 1: Guest OS and host OS: Windows 2003
ipconfig on guest: 192.168.175.128
I can ping this (guest) IP from the host machine, but get a "Reply from 192.168.203.186: Destination host unreachable" from any other machine on the network. I have tried this with bridged and NAT, with the same results.
It is clear that I am doing something wacky (given the discrepancy in the two IPs) ... but am not sure what that might be!
Any suggestions?
