Question : Static NAT for VideoConferencing Equipment

Hello All,

I have a Polycom VSX5000 unit that I would like to enable streaming on.
The problem is that the VSX5000 and the PC's I want to stream to are
not on the same subnet.

The PolyCom VSX5000 is on an external IP address. Say 1.2.3.4 (fictional)
The PC's are on internal addresses. Say 192.168.1.1

I have a Cisco router and switch that sits between the PC's and the VSX, and I'm assuming that I need to setup a static NAT for the VSX, How do I do this?

I have added a diagram which will hopefully help.

Answer : Static NAT for VideoConferencing Equipment

Hi,

Thanks for teh configuration.

A see, no accesslists so can use ACL 101 without problems.

The interface FastEthernet0/0 has allready "ip nat inside" this is ok. Is going to the switch.

And interface FastEthernet0/1 has already "ip nat outside" this is ok. Is going to the Internet.

So what you need to do is,

Copy this all and past it to the router, of cource after you put the right internal (192.168.1.1) and external (1.2.3.4) address !!!

***************************************************************************************
ip nat inside source static 192.168.1.1 1.2.3.4 route-map MAP extendable
!
ip nat inside source static tcp 192.168.1.1 1719 1.2.3.4 1719 extendable
ip nat inside source static tcp 192.168.1.1 1720 1.2.3.4  1720 extendable

!Define the port range
access-list 101 permit tcp host 192.168.1.1 range 3230 3235 any
access-list 101 permit udp host 192.168.1.1 range 3230 3235 any

route-map MAP permit 10
match ip address 101

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

The router will automatically put everything in place ....

Good Luck !!!
