We can't seem to get the clients on the 192.168.18.x OpenVPN tunnel (working for a long time) to talk to the External network.

The Lab Infra on 192.168.20.x does, however.

We've been through multiple articles on this forum and added in:

1. Firewall rules on the WAN- allowing port 4500 IPsec NAT-T) and ISAKAMP port 500
2. Firewall rules on IPSEC 142.233.210.0/24 to * * * *
3. Firewall rules on OpenVPN are wide open already as previously set up
4. We have two Phase 2 configs- a) LAN to External Network and 192.168.18.0/24 OpenVPN tunnel to the External Network
5. Added Static Route from the External Network to the Gateway External IP for our network.

Wondering if I need to set up an interface to bridge them or what as I need the OpenVPN tunnel clients to be able to get to the External Network like the Lab Infra clients can, so I'm confused about next steps.
