Securing some ports for a customer on their V2920 and having some problems. We are locking down RDP and OpenVPN to specific remote IP's and this works no problem as they are just simple open ports. We are then redirecting two ports (19851 & 19852) to two different servers internally both running SSH on standard port 22. However we cannot seem to get the filtering to work so that only a specific list of IP addresses can hit 19851 and 19852 and get SSH but nobody else gets a response. Can anyone tell me if this is possible and if so what rule to put in place on the firewall?
