@jimp:
Everything you need should be in the config.xml that you restore to the other system. Was the WAN IP address the same on the old and new unit? If it gets an IP by DHCP from upstream somewhere, it may have given a different system a different IP address.
If you need more detail in the OpenVPN log, just add "verb x;" in the custom options box, where x is a number. I think the default is either 2 or 3, you can go all the way up to 9, but you don't really want that much in most cases.
Yeah, same IP address (static from our ISP). I will try the verb option. Thanks.
