Unable to ping VM host (lima/colima)

### Description

I setup networking for lima/colima a few weeks ago and it had been working fine, but today, even after some troubleshooting, I can not ping the colima VM from my host. I have updated lima, colima, and macOS with patch releases lately, so that might be related, but I am not really sure what to check at this point.

On the mac I can see this:

```
bridge100: flags=8a63 mtu 1500
options=3
ether 16:7d:da:6a:3e:64
inet 192.168.105.1 netmask 0xffffff00 broadcast 192.168.105.255
inet6 fe80::147d:daff:fe6a:3e64%bridge100 prefixlen 64 scopeid 0x14
inet6 fdce:1812:ad25:915f:834:c0bf:f47f:b16e prefixlen 64 autoconf secured
Configuration:

ipfilter disabled flags 0x0

ifmaxaddr 0 port 19 priority 0 path cost 0
nd6 options=201
media: autoselect
status: **active**
```

but I can not ping `192.168.105.1`

One the `colima` VM, I can see this:

```
lima0 Link encap:Ethernet HWaddr 52:55:55:74:18:4D

```

and I can ping both `192.168.105.2` and `192.168.105.1`

I'm not sure exactly what the next step would be in figuring out what bit is likely broken.

Pointers would be much appreciated.
