I am unable to add a 1 to 1 nat entry. I have an existing one that is working but when I try to add another one in the same way, it gives me an error "Failed, please try again later.
Message: Failed to add". I have a /29 static subnet and I'm specifying an IP address within that range. My internal IP is in the routers standard 10.1.10.0/24 subnet. Neither the internal nor external address is used by my exising nat entry. I have tried resetting my router.
Thanks so much for taking the time to reach out to us regarding your 1:1 Nat concerns. I very much appreciate your patience and greatly apologize for the delay in our response. I know how important the services are to your business and we want to do all that we can to assist. Can you please reach out through private message with your first and last name, business service address and account number or phone number?
Did you ever get an answer to this? We tried to "change" one entry and "Failed Please try again later" Don't delete and entries, you will never get them back.
No, I ended up figuring out myself that I was able to turn off nat completely on the comcast router so at least it wasn't interfering and reconfigured to using the "true static ip" feature. Basically if you have another router or devices directly connected to the comcast gateway, then you can use your static ip directly with the gateway set to the gateway of your static IP subnet which is the first IP in the full netmasked range. I ended up getting a ubiquity ER4 which allows me to use all of my static IPs and control all NAT entries in much more flexible ways than the comcast router allowed.
Hi there, thank you so much for your feedback on what steps you took to resolve the issue and we do appreciate your time. Is there anything else that we can do for you or do you have any other questions or concerns regarding your account?
There is a way to add/change your 1:1 NAT Table. The source of the problem is the DHCP server addresses controlled by the routers DHCP. All of the LAN IP addresses must be in the range of DHCP addresses controlled by the router. STUPID, yes but after you setup the NAT table you can then correct the DHCP address limits.
For example our fixed addresses are in the 192.168.1.2 thru 192.168.1.32 range. 192.168.1.1 is the router itself. I must set the router's lower DHCP address to (in my case) 192.168.1.2 in order the edit the NAT table without getting the FAILED error.
After the editing the NAT is done I set the lower limit back to 184.108.40.206 and reboot.
