Cisco 1841 configuration

  Hello Everyone,

I work for a 2-way Radio company, We use Motorola equipment.  One of the systems requires a Router for each repeater site. Motorola recommends a HP MSR20-20 Router. I have set this router up before and it works great but I would like to be using cisco equipment vs. HP.  I'm having issues translating the way we program the HP router to the CLI on the Cisco 1841.  I would really appreciate any help someone is willing to offer.

Here's how the HP Router is setup in the CLI..   Thank you!!

int Eth0/1
  ip nat inside
  ip address 10.1.1.1 255.255.255.0
!
ip nat inside source static udp 192.168.1.10 55001 10.1.1.1 55001
ip nat inside source static udp 192.168.1.11 55011 10.1.1.1 55011
ip nat inside source static udp 192.168.1.12 55012 10.1.1.1 55012

I've set this configuration

I've set this configuration up and it doesn't seem to be working.   In this config,  I need all IP traffic from the 192.168.1.X network to be forwarded to the 10.1.1.1 Network.   

I should be able to ping 192.168.1.11 when connected to the 10.1.1.1 network using IP address 10.1.1.3.. Correct?

Thanks for your help!

Travis.

Hi Travis,

Hi Travis,

The rules suggested are for PAT. They are for forwarding single UDP ports. ICMP pings will not be covered by these statements.

Although I was not clear on your outside/ inside networks.

Instead delete the existing nat statements and try the following:

!
no ip nat inside source static udp 192.168.1.10 55001 10.1.1.1 55001
no ip nat inside source static udp 192.168.1.11 55011 10.1.1.1 55011
no ip nat inside source static udp 192.168.1.12 55012 10.1.1.1 55012
!
ip nat outside source static udp 10.1.1.1 55001 192.168.1.10 55001
ip nat outside source static udp 10.1.1.1 55011 192.168.1.11 55011
ip nat outside source static udp 10.1.1.1 55012 192.168.1.12 55012
!

I wouldn't recommend configuring static NAT on your outside interface to send it to a single internal host.

cheers,

Seb.
