I use 2821 with CCME. One of users need to connect external server on port 2000.
I use this config:
ip nat inside source list 1 interface GigabitEthernet0/1 overload
ip nat inside source static tcp 192.168.1.253 25 interface GigabitEthernet0/1 25
access-list 1 permit 192.168.1.0 0.0.0.255
Conection established but no data flow exist...
If I use IOS without CCME all work fine...
I suspect what problem is in port 2000, which CCME and Skinny default port.
How can I grant internal user (only one machine) access to external port 2000
and can still work with CCME?
Thank you much!
ip source-address x.x.x.x strict-match
and make sure the cme registration address is not in nat inside or outside interface.
If that doesn't work, try
ip source-address x.x.x.x port <2000 - 9999>
That will change sccp port, will require all phone to restar and register again.
Thank you very much...
But it does not work...
ip source in voice VLAN not int data vlan...
I heve solved problem
no ip nat service skinny tcp port 2000
Thak you very much...
