I'm having an issue with a Linksys RVS4000 which doesn't appear to be behaving as I think it should.
I need to forward a port (Single Port Forwarding) through to an internal NAT host. However, I only want that host/port to be accessible from one host on the internet, for security reasons.
I have created the port forwarding entry and this works fine. I then created two rules in IP Based ACL - one to block all access to that port from the WAN interface and one to allow access from a single host.
However, it appears that when a port forwarding entry is added, it will completely bypass the ACL and allow all traffic for that port/host by default.
Is this the correct behaviour?
Firmware version is v1.2.11
