My ISP puts the local router on IPv6 by default (resolved with a phone call fortunately), which I imagine is tunnelled through a number of IPv4 gateways as port forwarding doesn't work. It's the first time I've seen this.
- zamadatix 7y agoPort forwarding on v6 or v4? You shouldn't be port forwarding on v6 but if it was v4 it's likely they are using CG-NAT which basically results in double NAT which breaks such things. NAT64 would break this as well but I've only ever seen it in corporate networks or mobile networks.
