Outbound Traffic to LAN: Fail Without Sudo?

[jasonmvp]

I'm having an interesting problem with my M2 running Sequoia; it happened with 15.0 and is still happening w/15.0.1. Unfortunately my laptop is corporate managed, so there are limited things I can disable, shut down, work around. But I've started lots of conversations internally, including with our security folks, and none of them have seen this specific one: I can't connect to things on my LAN as a stupid-user. I can connect if I sudo to the superuser. That includes outbound pings, ssh, and even telnet (I installed brew's telnet). Get this:

deathstroke$ ping 192.168.10.10
PING 192.168.10.10 (192.168.10.10): 56 data bytes

Same thing happens if I try to ssh to that IP:

deathstroke$ ssh 192.168.10.10
ssh: connect to host 192.168.10.10 port 22: No route to host
deathstroke$ sudo ssh 192.168.10.10

I don't think this aligns with all of the security stuff that's been breaking with Sequoia. And yes, I even disable the Firewall, but to no avail. The wonky thing is, I can establish outbound to things OFF my LAN. I can ping them, too. See, Google's DNS:

deathstroke$ ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
64 bytes from 8.8.8.8: icmp_seq=0 ttl=60 time=8.074 ms

64 bytes from 8.8.8.8: icmp_seq=2 ttl=60 time=9.687 ms
64 bytes from 8.8.8.8: icmp_seq=3 ttl=60 time=6.915 ms
^C

round-trip min/avg/max/stddev = 6.915/8.366/9.687/1.014 ms

Works fine without the sudo.

This chump is stumped. Any ideas?
