Camera System Behind Firewall - Help

bn_enterp — Mon, 11 Mar 2019 10:36:35 GMT

I am fairly new to Cisco code, and am sure I am missing something simple. If anybody has any ideas, I would greatly appreciate any assistance provided.

I have an internal security camera server that I need to access from outside the network. The specific port the camera software uses is 32001 and the server has been assigned a static address of: 192.168.1.100. I have a PIX 506E.

I have tried several things, but cannot seem to get it to work. I cannot get it work inside the network either, so there is something blocking it there as well. I have added everything to the access-list I can think of, but nothing seems to be working. I have tried adding the following code and several other lines similar to this and it will not work:

static (inside,outside) 206.206.206.207 192.168.1.100

conduit permit ip host 206.206.206.207 eq 32001 any

access-list 101 permit ip any host 192.168.1.100

Below is my config.

First of all, if it does not work from the inside when you are trying to access 192.168.1.100 on port 32001, you will not get very far getting it to work from the outside. Here is the config you need though for the outside access if you were using your pix outside interface address to access the server...

no access-group 101 in interface outside

static (inside,outside) interface 192.168.1.100 netmask 255.255.255.255

access-list outside permit tcp any host 206.206.206.207 eq 32001

access-list outside in interface outside

Also, do you have an inside router routing between 192.168.0.0/24 and 192.168.1.0/24?

This route statement is not correct

route inside 192.168.1.0 255.255.255.0 192.168.1.1 1

It needs to point towards another address on the 192.168.0.0/24 network.

route inside 192.168.1.0 255.255.255.0 192.168.0.x

I would also get rid of this as it's not needed

no access-group 101 in interface inside

This is a remote location from our corporate office, and there is a router and a switch in addition to the PIX. The switch has 2 seperate VLANS, one for our corporate users that can only get to our VPN server and one for vendors/outside users that just need to access the internet.

The corporate users are assigned a 192.168.0.X address, vendors are assigned a 192.168.1.X address.

I thought there may be something blocking it in the PIX from working internally while I am on the 192.168.1.X network.

The traffic would not be hitting the pix for communication between a client on 192.168.1.x and the camera server 192.168.1.100.

Try pinging the server from a client and from the pix.

Yes, that is true, that makes sense. I may have something else going on, but my main goal is to get it accessible from outside the network, there will not be any need to access it internally.

I will try what you posted in your first response and see if I can get it working.

Thank you for your input.

Any luck?

The system is at a remote location and I have not been able to get there to try anything yet. I am hoping for today or tomorrow. I will post the results.

Thanks
