I use an EE SIM card for a failover service (Primary on Vodafone) on a 3G router to transfer data by ftp on some mobile equipment.
This requires me to create a Port Forwarding rule on a firewall to receive the data. Every day I have to change the rule to allow for the change in IP address.
For Vodafone I have the IP and Subnet ranges to allow through the port forwarding, but i cannot find this information for EE.

Hi @simon0275
Welcome to the community.
Our mobile data network uses dynamic IP address, so they're likely to change frequently. I'm not aware of any way to use those subnet ranges. There may be another community member who comes along that does though.

@simon0275 : Port Forwarding works on the internal private IP addy of the LAN device running the server listening on the port being forwarded. The external public IP addy of which others speak has little or no bearing on this.
Most EE mobile routers have a LAN IP subnet of 192.168.1.x . Some may have their subnet & range changed, some can't (Osprey, Yes; 4GEE Wifi, No). Which EE mobile router have you?
To help me better understand your enquiry:

Hi Chris
Thanks for your response, we are aware that dynamic addresses are used. EE must have ranges of subnets that they allocate these addresses from so we can add those to an allow list on our Firewall. Otherwise we have to allow any IP, and we'd rather reduce as much as possible. Vodafone Helpdesk were able to supply this information, I've tried a few ways but not been able to get any help from EE.
Thanks

I can't think of a exhaustive way of doing this other than by trial & error as follows:
Whenever you make a connection you are given an individual public IP addy. If you look up its WHOIS on WHOIS Lookup and Domain Name Search it will give the full IP range of the pool from which it fished out of. However EE has many such pools which historically started out for its particular diff networks but now EE seems to pull them out indiscriminately from any of them.
