I've just got a new firewall that I'm configuring up on a Linux system and I'm trying to get the SureSignal to work with it. I've opened up port 500, 4500 and 123 UDP through to the SureSignal from the Vodafone specified IP addresses for complex networks as specified here - http://help.vodafone.co.nz/app/answers/detail/a_id/12608/~/set-up-complex-networks-with-sure-signal, however the SureSignal still won't connect via the NAT masquerading on the Linux Firewall. What am I missing?
When I monitor the inbound traffic from the Vodafone network I see strange traffic on protocol 17 showing up with no port id at all and it's not being passed inbound. I'm using CentOS 7 and firewalld to control the iptables.
Any tips of what other ports / protocols I need to allow to get the SureSignal to pass through the NAT Firewall would be greatly appreciated.

Correct. It will work if it's directly connected to the Vodafone UltraHub, but it won't work via the Firewall. All the ports documented by Vodafone have been opened. But it won't authenticate for some reason. Once the connection is established if I reroute the traffic via the firewall everything works fine until the IPSEC Tunnel is restarted.
