I'm a PLC programmer and I'm afraid I might be out of my depth here. PLCs generate too much traffic and need to be kept seperate from a comapny network. However I need access to the PLC from the campany network for monitoring and programming reasons. I thought a 1 to 1 NAT using static numbers would work, but I can't get it to communicate both ways. Here my test set-up:
Laptop --> WAN port of TL-R600 --> LAN port of TL-R600 --> Computer (Spud6)
static IP of 10.10.10.1 static address, 10.10.10.38 static address, 192.168.1.31 static address, 192.168.1.107
subnet 18.104.22.168 subnet mask 255.255.255.0 subnet 22.214.171.124 subnet mask 255.255.255.0
There is one entry in the 1 to 1 NAT in the table:
|ID||Name||Interface||Original IP||Translated IP||DMZ Forwarding||Description||Status|
From 192.168.1.107, I can ping 192.168.1.31, 10.10.10.38, and 10.10.10.1
10.10.10.1 cannot ping any address on either side of the router.
Have I missed something simple, or am I trying to do this the wrong way?
