I'm having a little trouble getting the firewall features on the RV016 setup properly. I've got four WANs running and a single (the default) VLAN. I'm trying to restrict RDP access for SERVER1 to a specific range of IP addresses over WAN1, and RDP access for SERVER2 to a specific range of IP addresses over WAN2. I've setup the access rule, but it doesn't make any difference, RDP doesn't work. Even if I set the access rule to allow any IP on any WAN to RDP, it still doesn't work.
If I go up to the forwarding section, I can forward all RDP over to SERVER1, but I can't restrict what range of IPs go to it, and then of course I can't get into SERVER2.
From my understanding you have 2 servers that need multiple RDP instances on them. Currently this router has a limitation as its not able to do Port translations. PAT would allow for multiple different external ports(such as 3389,3390) to internal port 3389 on both servers. If your network allows one to one NAT could really help with your situation.
The one to one Nat functionality will opens all ports and anyone can get to the servers. So to fix this issue you would create permit and deny statements.
First permit/allow source ip and dest ip(servers) service 3389. Following the permit statements for both server you would create a deny any rule. I now have not been as detailed, let me know if this helps you.
I've tried this, but I only have the one static IP address for each WAN. When I try to setup the one to one NAT, it won't allow me to use the IP address because it is taken by the router. Do you have any other suggestions?
The one to one Nat is our last option on this router. It will only work with a range of public ip addresses, which goes for all small business routers. Do apologies for the inconvenience. An RV130 will accomplish the port forwarding you are trying to do with RDP. Though i suggest this as ISP would charge for those extra public ip's for the one to one nat.
