hi team!
i setup a middle relay & i get this:

sudo journalctl -e -u tor@default

Unable to find IPv4 address for ORPort 443. You might want to specify IPv6Only to it or set an explicit address or set Address.
Now checking whether IPv4 ORPort my-ipv4-public-ip:443 is reachable
Now checking whether IPv6 ORPort [my-ipv6-server-ip]:443 is reachable
Self-testing indicates your ORPort my-ipv4-public-ip:443 is reachable from the outside. Excellent.
Self-testing indicates your ORPort [my-ipv6-server-ip]:443 is reachable from the outside. Excellent.

Is it normal i get my public-IP address and not my server-IP in IPv4? in IPv6 i get my server-IP
why it told me this if self-testing said Excellent ?: Unable to find IPv4 address for ORPort 443

/etc/tor/torrc
Nickname    myxxxxxxxx
ORPort      443        
ControlPort 9051 
CookieAuthentication 1

i had read this :
If you are behind a NAT, use two ORPort lines: ‘ORPort NoListen’ and ‘ORPort NoAdvertise’ should i add this to my torrc file

ORPort public-ipv4:443 NoListen
ORPort server-ipv4:443 NoAdvertise

In order to make it work you need to do port forwarding on your router for port 443
public ip:443 → local server ip:443. (at least this is what i did on the servers behind NAT)

I don’t think adding that new lines to config will help you with something.

thx for you help

Yep i did forward my port from my router to my server

i’m wondering why tor show me my public-IPv4and my private-IPv6(server IP)

Self-testing indicates your ORPort my-ipv4-public-ip:443 is reachable from the outside. Excellent.

and if i modify my file torrc

/etc/tor/torrc
Nickname    myxxxxxxxx
ORPort      192.168.100.100:443

i get the message

If you are behind a NAT, use two ORPort lines: 'ORPort <PublicPort> NoListen' and 'ORPort <InternalPort> NoAdvertise'

Just leave the port in the /etc/tor/torrc no need to specify also the port

Nickname    myxxxxxxxx
ORPort  443

As for your IPv6 question i am not an IPv6 expert but i think it is related to the way your server gets IPv6 from the ISP, SLAAC in this case.

thx for the help SirNeo
I will run it with only ORPort 443and see
