I've been trying to get a simple route working in Parallel Desktop for days with zero success. I had a similar setup working in Mohave using an older version. Setup: I have a linux router running on the host-only virtual network at 10.37.129.3. The host OS, Monterey, is at 10.37.129.2. I just want to route traffic through the linux router. The routing table looks fine: Code: > netstat -nrf inet Routing tables Internet: Destination Gateway Flags Netif Expire default 10.37.129.3 UGScg bridge101 default link#19 UCSIg bridge100 ! default link#21 UCSIg bridge101 ! 18.104.22.168 link#21 UHLWIg bridge101 ! 10.0.0.12 link#21 UHLWIig bridge101 ! 10.37.129/24 link#21 UC bridge101 ! 10.37.129.2 b2.be.83.d5.0.65 UHLWIi lo0 10.37.129.3 0.1c.42.87.1e.68 UHLWIir bridge101 1075 10.37.129.255 ff.ff.ff.ff.ff.ff UHLWbI bridge101 ! 10.211.55/24 link#19 UC bridge100 ! 10.211.55.2 b2.be.83.d5.0.64 UHLWIi lo0 10.211.55.255 ff.ff.ff.ff.ff.ff UHLWbI bridge100 ! 127 127.0.0.1 UCS lo0 127.0.0.1 127.0.0.1 UH lo0 127.0.0.2 127.0.0.1 UHW3I lo0 2068 224.0.0 link#1 UmCS lo0 22.214.171.124 link#1 UHmW3I lo0 3471 126.96.36.199 1:0:5e:7f:ff:fa UHmLWIg bridge100 This output looks good, too: Code: > route get 188.8.131.52 route to: 184.108.40.206 destination: default mask: default interface: bridge101 flags: <UP,DONE,CLONING,STATIC,IFSCOPE,GLOBAL> recvpipe sendpipe ssthresh rtt,msec rttvar hopcount mtu expire 0 0 0 0 0 0 1500 -1408 Running tcpdump on the router I can see when Monterey pings the router, but there is no traffic if I set it as the default gateway. I can also use the linux router as the Windows 11 default gateway just fine, so the router doesn't appear to be the problem. Anyone have any suggestions?!
