NAT problems on Cisco 890

Hey everyone

Ok, here is the problem.

I have a CISCO 890 router and I can setup port forwarding and the people from the outside can get to the servers with no issues, but the people inside the network cannot get to the local server using the public IP address.  Now, here is where it gets tricky.

The server in question is an IP camera server, and so its not on the domain nor does it get its DNS from a local DNS server.  Of course, now that I mention all of that, I will have to ask the camera guy if the PC could join the domain and use the local DNS server.  But, if that cannot be done, is there a way to setup NAT loopback (if thats the proper term) on a CISCO 890?

Now, here is the crutch of it all.  Right now they have a RVO42 and it works fine.  They are trying to upgrade their router and the 890 was the one that they picked out.

Thanks for any help!!

Why not use a network name for the camera and configure your DNS to point to it?

that would be a reverse setting right?  or a forwarding setting in the DNS?

Forward - as your clients query camera_name.domain.local

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Naw, didnt work.  What I dont understand is this.  How can a Linksys RV042 router do this without making anything special, but a Cisco 892 cant do this?

Can anyone out there tell me this?

What I do not understand: Why are you acessing it from internal with a public ip?

The camera system requires it. I asked the camera guy and he said that the software is setup that way. Is it dumb?  Yes

What is the local subnet and route information on the 890? Do you have seperate VLANs configured on the 890 for the inside networks?

No. Same subnet. Should I put them on separate VLANS?  Damn. Didn't think of that. Local subnet is 192.168.1.0 - 255. The DHCP is from the router and is 50 - 255. Left the lower ones for the servers and printers.  I am on my cell now so I don't have the rest of the route configuration. I can post it here later

Ok.  The customer came up with a solution.  They went ahead and purchased another Internet connection from Comcast.  They will put all of their security cameras and DVR one one network and their PC's, servers and printers on a separate one.  Made my life much easier :-)
