When you try to connect with the UTM in place does the vpn fail to connect or you can connect just not browse?
It would be helpful to see logs from the firewall, ips, web filtering as there should be a clue there if the UTM is dropping or not allowing the traffic out.
What port are you using for Openvpn?
Do you have https scanning enabled as it could interfere with traffic on port 443.
A NAT masq rule and a firewall to allow Internal Network -> any -> Internet should be all that's necessary for basic functionality.
dilandau said:Yes, the Internet object is the same as ANY but is bound to the Interface with the Default gateway. So it only always traffic that traverses the External Interface.
What if there are 2 external interfaces, and the one designated as the default gateway is NOT the one the traffic sould go through,
how the firewall rule should be then?
It cannot be AnyIPv4, it cannot be InternetIPv4, what should it be ?
External(Address) or External(Network) or ???
Thanks.
The Traffic Selector would be 'Internal (Network) -> {Services?} -> Any' for a WAN connection without a default gateway.
Back before we had Uplink Balancing with Multipath rules, we had to use Policy Routes to get traffic to go out a second WAN interface. I would give your second WAN connection a default gateway and use Multipath rules to select which traffic should go through which connection. This would make your existing WAN-1 firewall rules also work for WAN-2.
