I am in a bit of a quandry. I have recently got a 1841 security bundle with a T1 wic.
I have been trying to set this up a certain way and I don't think that I can do it. Here is a little background info.
I have a Point to Point Frame Relay T1 coming from an ISP. I am only using 1 ethernet interface on the router, eth0.
Here it is right now
68.xxx.xxx.185 ISP network/gateway of last resort
68.xxx.xxx.186 IP address of serial interface/"Outside" interface of router
192.168.2.254 IP address of eth0 interface/"Inside" interface of router
I created a pat entry so 192.168.2.x will translate to the outside interface. I am able to ping the ISP network and browse the internet from the inside interface.
Here is where it gets a little complicated for me. I am now given a polycom that needs to be accessed from the outside (right now I am not worried about firewall ACL's, that is a different conversation).
My ISP has given me 6 public IP address that I can use: 207.xxx.xxx.57 - 62. This is what I have done so far. I gave the polycom the address of 192.168.2.1 and made a static nat in the router of (inside) 192.168.2.1 to (outside) 207.xxx.xxx.57. Please forgive me, I am using the SDM for all of this.
I can initiate a call to another polycom on the internet and establish a connection but I cannot answer a call orginating from the outside destined for my polycom.
At first I thought it may have been the firewall or QoS on the router, but I have disassociated all of that from both interfaces.
Then I thought that a static route was needed to send the packets to the polycom.
I setup the route from public ip to polycom ip and I still can not receive a call.
I initiate a call and go to the cli and run: sh ip nat translation <cr>
and it appears that the polycom traffic is getting translated to the 207.xxx.xxx.57 ip address.
I am at a loss. I don't want to setup the inside interface with a 207.xxx.xxx.63 address if I can help it. I was hoping to be able to get more use out of the T1 besides just for the polycom.
Can I set the router up in the fashion I have tried to explain or is it supposed to have the public ip on the inside interface and get PAT'd futher back in the network?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
