My bitcoin node is receiving connections from
2a00:1398:4:2a00::a1
2a00:1398:4:2a00::a5
2001:0:4137:9e76:2877:25aa:51c2
on port 8333
I dont understand how I am receiving this connections because I have port 8333 closed in my ADSL router.
I have tested from
https://bitnodes.21.co/ to check my node and it says it is not available, which is correct as I say the port is closed in the router.
So, how can my node be reachable by those addresses at port 8333 ? May be because IPv6 and an error in my router ?
PS: in case it helps: user-agent for that connections is Satoshi:0.9.99
Maybe these connections are going through a different port into your node.
If you want me to, if you send me your IP (via PM) I'll test your 8333 port to check nothing is live through it. If you don't want to share your IP then that's fine also.
