@normis: I don't remember a lot of it clearly. Some parts are a little hazy. I was rushing so bad on adrenaline, and trying to keep the shark from eating us both. It made a few passes at us on the way to the beach. Very bad.
For those that are interested, Discovery Channel's Shark Week should be on in Early July. My episode is "Shark Attack: Predators in the Panhandle". Don't venture too far from shore without a way to get completely out of the water!
ADD: If you have DNS challenges with the email server, you can set that localnet ip for the server.
/ip dns static
add name=mail.mydomain.com address=192.168.0.2
Change the name to the domain name and address to the localnet address of the email server.
This changes only localnet dns. External dns will still resolve to the public ip. This dns change is effective even if the client computer does not have the ip of the router set in its dns settings.
Insure the email server is set to relay outbound email for your localnet ips. All subnets. If your email server was set to relay email for just the subnet it was on, that would explain why it would work with a masquerade, but wouldn't without it.
