Device on LAN ping returns gateway, (other vlans fine)

[rt050]

Hi All,

First of all, what a great product Opnsense is, thank you :)

I have a problem that has developed this morning after playing around with Zerotier (really cool stuff).

So right now, I'm connected to my firewall via OpenVPN and I can ping and access the firewall and GUI. The hosts on this subnet however, is returning the gateway address. Weird.

For example:

Pinging 10.20.8.1 with 32 bytes of data:
Reply from 10.20.8.1: bytes=32 time=20ms TTL=64

H:\>ping 10.20.8.101

Pinging 10.20.8.101 with 32 bytes of data:
Reply from [MY_PUBLIC_GATEWAY_IP]: Destination net unreachable.

Now, this server is in a datacentre and it's a self contained host. Everything has been up for a few months, no issues at all.

Initially I configured Zerotier to talk to my remote subnet, worked well. Still works but I tired to add a route to LAN (10.20.8.0/24) and now the devices are offline and I can't ping or anything.

What I've done so far:

I can ping from LAN interface on Opnsense
I can access the firewall via VPN and devices on other subnets work/are online
Verified I haven't changed any rules
Disabled all Zerotier config and interfaces to see if that helps.

I haven't rebooted Opnsense, I'm hoping to fix this without resorting to that, plus the ESX gui is on the "misrouted" subnet  :'(

I suppose I could try and remove the LAN interface and re-add it with the same IP range. ESXi is statically assigned.

I'd really appreciate if anybody has any pointers.

Thank you
