Switched ISP, PPPoE to DHCP
-
@f022y You are behind carried grade nat.
This is where 100.x is used for.
Unless your new isp can switch you to "public" ip, nothing related to port forward will ever work. -
@netblues Thank you for the reply, i had a horrible feeling that would be the case.
-
@f022y CGNAT only applies to IPv4, see if they can get you on an IPv6 address.
Doubtful, but worth a try. -
@jarhead one can get a tunneled ipv6 from hurricane, but the whole point is most probably irrelevant to the op.

No, what I meant was from his ISP. If they have IPv6 capabilities he wouldn't be behind the CGNAT.
Problem is, not many ISP's offer v6 yet. -

WAN interface on pfsense = 100.64.x.x
Yup, CGN. That will prevent any port forwards working. So likely the firewall rules are actually fine.

So got an email today from their support to confirm CGNat is used but i can buy a static IP for a monthly fee I see on their website they support IPv6 so asking about that.
-
@f022y Getting a static ipv4 is your only viable option
Life with ipv6 only needs also some kind of nat upstream, if you are to be connected to the Internet as we know it.Sad but true :)

@netblues bugger. Annoyingly since discovering CGNat (i'll be honest never came across it in the UK must have been lucky) this explains a few things.
Since switching i've had strict NAT on my PS5 which i've not been able to work out, previously I would look at port forwarding to fix but obviously i now know why that didn't work.
-
So after a chat with my ISP they offered me a free public IP, all my rules work again!!
Thank you all for the help i'd never come across CGNat before. The more you know.
