HTTP; 25, SMTP; 110, POP3.

be greater than that specified in the previous field. If Local Port Start is left at

Remote Policy Remote IP addresses must be static and correspond to the remote IPSec
router's configured local IP addresses. The remote fields do not apply when the
Secure Gateway IP Address field is configured to 0.0.0.0. In this case only the
remote IPSec router can initiate the VPN.
Two active SAs cannot have the local and remote IP address(es) both the
same. Two active SAs can have the same local or remote IP address, but not
both. You can configure multiple SAs between the same local and remote IP
addresses, as long as only one is active at any time.
