Hello,
to give our users the remote access with the GW client through BM3.8 to our
static NAT GW7SP1 Mailserver I opened port 1677 in both directions (from
public interface to private (host=mailserver) STATEFUL and vise versa). Is
these a critical port, or is there a way to do this in a more secure way?

Thanks for your suggestions.

Regards
Mirko
