|I'm not sure if this is considered "advanced" networking, but it is at least a little more complicated than the plain and simple port forwarding.
I want all incoming Internet traffic on port 1000 (TCP) forwarded to 10.0.0.10:1000 (TCP). However, I want to limit this to a specific egress port on the built-in switch in the wireless router.
This is for security reasons. I don't want a scenario where for whatever reason the IP for the computers on the network have changed, and the traffic gets sent to the wrong computer.
Can this be done with dd-wrt? Does it depend on the device dd-wrt is installed on?
It seems this should be quite similar to the iptables command -o, --out-interface
But I don't have an interface per port.
I only have: ath0 ath1 br0 eth0 vlan1 vlan2, this is for a TPLINK TL-WDR3600.
