We have an SMC Gateway at one of our sites. We've set up port forwarding to remotely manage our NEC PBX. It's got a static IP address of 10.1.10.100. Port 8081.
Everything was fine when we set it up, but our access to the PBX was soon blocked.
When the SMC is reset, we can get into the PBX for a few minutes, but very soon we lose access.
Why is this happening? Can anything be done on your end to help us? We need to get to this device from time to time!
I believe that 10.1.10.100 is the start of the DHCP range for dynamically allocated devices on the SMC; have you checked that this specific address is excluded from the DHCP address pool?
I will say that it has been my experience that the Comcast rental gateways function best when they are connected to a separate router that manages port forwarding & other routing options. The SMC is best either in bridge mode or provisioned with static IPs, with your router using one of the statics.
Thanks! I'll check it out ASAP.
Anyway, I don't think we're going to be able to do anything about this. We're not getting a seperate router any time soon...
I'm going on vacation in a few days, so will get back to you next week, if anything gets resolved.
The SMC and NetGear DCHP start address is 10.1.10.10. You can use 10.1.10.2 through 9 for any device for it to have a non-dynamic IP address or psuedo static.
Hope this helps you out.
