It could be that your new ISP uses CGNAT https://en.wikipedia.org/wiki/Carrier-grade_NAT

Browse to https://ifconfig.co and see if the public IP matches that on your firewall.

If you do suffer from CGNAT, you may need to think about alternatives. I've used Cloudflare tunnels in similar situations: https://github.com/cloudflare/cloudflared

Try this? There are many YouTube videos as well: https://docs.ibracorp.io/cloudflare-tunnel/
