Not able to route traffic to vm

[RyanTsang]

Hi,

There is a network range 198.19.0.0/16 in the vm. I want to set up a route record on my host to route traffic to this ip range in the vm.

vm yaml: basically same as the docker-rootful.yaml example, except for the network section

...
networks:
- lima: host
...

host machine info:

 $ uname -a
Darwin Ryans-MacBook-Pro-2.local 21.6.0 Darwin Kernel Version 21.6.0: Mon Aug 22 20:20:05 PDT 2022; root:xnu-8020.140.49~2/RELEASE_ARM64_T8101 arm64

my vm ip: 192.168.106.2. and I am able to ping this ip from host

 $ ping 192.168.106.2
PING 192.168.106.2 (192.168.106.2): 56 data bytes

routing rule on host

 $ netstat -rn|grep 198.19

198.19.0/16        192.168.106.2      UGSc        bridge101

when I try to ping 198.19.254.1

 $ ping 198.19.254.1
PING 198.19.254.1 (198.19.254.1): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1

^C

I used Wireshark to monitor ICMP traffic, but I can't see anything. I am assuming my host is not routing the traffic properly.

Thank you all in advance.
