Ubuntu to Sophos xg210 setup

Hi,

 

I've inherited a very old Ubuntu Firewall and need to transfer everything on it, to our new Sophos Firewall...is there a simple way of doing this, or is it literally one NAT rule by one NAT rule?

 

Having viewed the NAT and port forward rules in Ubuntu, there does seem to be rather a lot, plus a bunch of routing and interface rules and one masquerade rule that I can't necessarily see options for in the Sophos Firewall

 

I have an internet connection out on a spare line so I can keep it online while I do this. It does at least get out to the internet under the default policy that came with the Firewall. However if there was an import for the rules... that would be helpful.

 

Any help appreciated.

 

Many thanks.
Dave.
