Title: Can't telnet router from behind server-gateway
Post by: Mike Coan on June 02, 2003, 10:01:54 PM

Previously I had Mitel SME 5.6 (with updates) running in server only mode.  I added a NIV to the SME machine and configured it for Gateway-server mode.

Everything works fine.  The internal NIC has address 192.168.1.1, and the external NIC has address 192.168.3.1.  the router is an Effcient 5851 for a SDSL connection.  the internal ip of the router is 192.168.3.254.

I can ping 192.168.3.254,  I can use the Windows configuration GUI that comes with the router to log into the router, but I cannot telnet into the router, either from my workstation (using Linux) or from the e-smith server-gateway box.  Most of the router configuration is done with a command line interface.  the GUI is pretty limited.

Thanks for any pointers

Mike

Could the router only be accepting telnet requests from a certain MAC, namely that of your old machine?  Maybe you could reset the router configuration?

Just some thoughts,
Nathan

Thanks Nathan.

I forgot that I had restricted telnet access to the range 192.168.1.1 to 192.168.1.253, the range of the private network.  When I set up the SME as server gateway, the external NIC had an address of 192.168.3.1.  I guess telnet from my machine was treated as comong from 192.168.3.x, and that wasn't permitted.  Once I enabled the range of 192.168.3.x as having telnet access, all was fine.

Thanks again.
