[Simh] Networking help with 4.3 BSD Quasijarus running on SimH microvax

This may be an obvious question, but is your Mac connected via Wi-Fi? If so, you’re going to have problems using the default networking. I tried to do this several years ago, and never found a totally satisfactory solution. I figured it was worth checking, because if this doesn’t work nothing more advanced is going to.
Best,
Zack.

After the system comes up completely, I log in as root and ping yahoo.com - no result. I ping 192.168.0.1 (my gateway), and then 127.0.0.1 and get a result, but it's not what I'm hoping for -
