System information

Erigon version: 2.43.0
OS & Version: Ubuntu 22.04
Chain/Network: Eth, Polygon... etc

Expected behaviour

The NAT parameter no longer seems to work as intended.

Using for example nat=extip:1.2.3.4
... should result in an enode address with IP of 1.2.3.4

Actual behaviour

Instead, it just shows 127.0.0.1. The port also shows as 0, so it's unclear if one or more parameters such as '--port' are also faulty.

self=enode://xxxxxx@127.0.0.1:0 name=erigon/v2.43.0-stable-1106475e/linux-amd64/go1.20.3

Therefore, it's currently not possible to set a valid external IP:port for peering. The assigned IP set by the flag seems to work for the torrent feature though, according to the startup logs ([torrent] Public IP ip=1.2.3.4).

Everything was working on v2.42.0, tested on a few different nodes on both Eth and Polygon, before and after upgrading.

Steps to reproduce the behaviour

Use the nat flag to set an external IP: --nat=extip:${PUBLIC_IP}
