Hi. Can anyone tell me if the Firewall has an effect in passthrough-mode?
I have a situation where a firewall is behind a RUT240 with an active 4G interface. In NAT mode, the firewall can establish a site-to-site VPN with another remote firewall. However, when using pass-through, the VPN will not establish, even though the remote firewall does respond to ICMP.
I'm wondering if the firewall on the RUT could be blocking something?
