Hi,
I appreciate that NAT routers will differ in their specification, but I think this is a generic question. For info, my router is a Draytek Vigor 2800v.
Do NAT routers only block ports above 1024? Or, to put it another way, do I have to explicitly open/redirect ports below 1024?
Thanks.
Bob
You will specifically open the desired port and point it to the computer that will be handling that service.
Thanks. So that applies to reserved ports such as 22 (ssh), 80 (http) and 443 (https), as well as the tens of thousands of higher number ports?
Bob.
Normally, firewalls apply to the first 1024 ports as they're reserved for the various service. However, regardless of which port you're using, you'll still have to forward it appropriately. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
