I have a static IP internet connection through a Draytek Vigor 2860 router.

On my network I have 2 cell phone booster boxes that both require port redirection on ports TCP 50, UDP 123, UDP 500 and UDP 4500.

One of the devices works but the other doesn't. At present they are both set up with their own local fixed IPs and relevant ports are redirected to them in the router settings.

What am I doing wrong please?

It is working the way it is designed. You only have a single IP address is the main problem. Each ip address only has one of each of those ports.

Many times applications can be designed to accept other port numbers so you can use different ports for different applications. The main issue is someone actually has to design applications to accept other ports. These ports appear related to ipsec vpn. There is nothing saying the manufacture could not use other ports but it appears they have decided to only support the standard ones.

Still there are special problems with VPN like ipsec or even simple GRE tunnels. These are not actually ports. The so called PORT 50 in your list I suspect is not actually a port but PROTOCOL 50...

The so called PORT 50 in your list I suspect is not actually a port but PROTOCOL 50 which is also used by IPSEC. Many routers have a special feature to allow these protocols to work and in most cases the router just does it you do not have any ability to set anything. The router will either support it or not.

Still you are doing nothing wrong. You just can not accomplish what you are attempting. There really is no solution if the providers equipment does not have a solution to running 2 devices behind the same IP address.
