Upgrade from 1.2.3 to 2.02

[SMuD]

I am trying to replace a 1.2.3 system that was built in 2009.  I can backup and restore the firewall rules just fine, but the NAT does not import correctly.  When I try to import them I get config errors showing in the status window.

Do 1.2.3 NATs work on 2.02 builds?

I have tried recreating these manually - so… can someone please explain the difference between Internal IP and Destination IP under 1:1 NAT?  Should these not be the same thing?

If I want my system with an IP of 1.2.3.1/28 to forward traffic for 1.2.3.4 to the LAN address of 10.10.10.10 I get that 1.2.3.4 should be my External IP, 10.10.10.10 should be my Internal IP but why do I also need to specify a Destination IP?  Am I safe in setting that to "Any"?

Thanks!

The config should import OK unless you happen to have international characters somewhere. See http://doc.pfsense.org/index.php/Upgrade_Guide#International.2FSpecial_Characters_in_1.2.x_Configs
