Configure port range Forwarding on Cisco 887

[r.brahmi1]

Hi,

Please I need help

I want to redirect a port range from 49152 to 53246 in a Cisco 887 router, these ports relate to a VOIP application from Avaya,
the internal address which I am forward ports is 10.100.118.3
Please who can help me on this, I searched a lot but I have not found concrete response

I know redirect a single port
example
  ip nat insite source static tcp 10.100.118.3 22 interface dialer1  22
but a range of ports I do not know

Thank you.

Hi

there is no range command in NAT unfortunately so the workaround is you can use a route-map and match against an ACL with ports

Just an example you may need to tweak it

*************************************************

ip access-list extended TESTRANGE1

permit tcp host 10.100.118.3 any range 49152 53246

!

route-map TESTRANGE permit 10

match ip address TESTRANGE1

!

ip nat inside source static tcp 10.100.118.3 route-map TESTRANGE
