Hi there,
I have a ddwrt router setup as a gateway to my network.
Is it possible to setup a configuration where traffic coming from generally useful services (ports 80, 443, 21, 22) to go through to the clients via the NAT at full speed, but limit the bandwidth for traffic coming in to all other ports to an arbitrary preset amount (say 256Kbps).
This is mainly to discourage the use of non-essential services on the network while keeping compatibility with services that use non-standard ports (albeit slowly).
My intention was so that users can access HTTP, HTTPS, FTP and SSH remote services at full speed while having a restricted (but still functional) access to ANY other services they may need to access.
