Port forwarding issue

[Shnorkiller]

Hi All,

We have been brought on board to help a non profit organisation setup a hotspot service on a sponsored fiber line, they want it purely for administrative purposes i.e who has internet access and capping/shaping etc.

The problem is that we have only dealt with ADSL lines that we have installed (or have had access to the router) in order for us to configure the required port forwarding.

We've been issued with a static IP for the hotspot, but do not have access to the cisco router installed by the sponsors in order to setup the config that we need. When speaking to a network administrator who organized their sponsored line he couldn't understand why we needed ports to be opened and was pretty clear that there was no way he was going to be able to do anything to help us.

So here is the question, is there a possible work around for us that would not require us accessing the cisco router in order to set up the port forwarding that (to my knowledge) is required?

Thanks so much to anyone who can help!

Use another router and connect it to the Cisco?

Depends. Do you need incoming ports to ignore the NAT and go straight to the forwarded destination?
If so (probably is), then you are in quite a pickle my friend.

If working with the NAT is okay, then put another router between your hotspot and the cisco router.

Funny though, with a static IP one would expect you'd have access to the port forwarding rules.

In most cases with a fiber connection the provided does not enable NAT on their router unless you have specifically requested it. It's therefore not possible for them to do port forwarding for you. You should use the static address or range that has been issued to you on your own router.

If you are using a MikroTik for the hotspot then this should be relatively easy. Just configure the public IP address on your router. Use the Cisco IP address as your gateway. Configure a NAT rule using the srcnat chain, set the action to src-nat and to address will be your public IP.

Forwarded ports typically are sent to a static IP on the LAN. E g. VNC.

Why do you need it? It will help to answer your question if we understand the application.
