NAT U-Turn does not work on 2911 router
Hello,
Consider this scenario:
- 1. Both Host A 192.168.1.70 and Host B 192.168.1.70 have Router A 192.168.1.1 as the default gateway
- 2. The network 192.168.1.0 /24 is NAT ‘d to the address 10.10.10.10
- 3. There is a static NAT (port forwarding) for port 80 on IP 10.10.10.10 to 192.168.1.30
- 4. Host A 192.168.1.70 ties to access web-server Host B by going to port 80 on 10.10.10.10
The connection fails. Is there any method to make this work?
Regards,
AA
