Dear experts,

I have a special question, for which I could not find 100% clear documentation after a research.

Situation:

- VPS with more than one IPv4 and IPv6 address

- IPv4 within the VPS is private class-A only (i.e. 10.x address), so port binding happens to the private Class-A

- External IPv4 is linked outside the VPS to the private Class-A - of course, VPS is externally reachable by the external IPv4

- I would like to use a secondary IPv4, i.e. NOT the one, which is shown, when you run the command 'curl -4 icanhazip.com' from within the VPS)

- I would like to use a secondary IPv6, i.e. NOT the one, which is shown, when you run the command 'curl -6 icanhazip.com' from within the VPS)

Let's assume, for my example only, I have the following secondary IP addresses :

- external IPv4 7.8.9.10

- internal IPv4 10.0.0.7

- IPv6 [2345:bad:face::]

Let's further assume, my ORPort was 1234 and the obfs4 port was 4321

In order to have TOR distribute the correct bridge line "obfs4 7.8.9.10:4321 <...>", 

is the following torrc config correct?

BridgeRelay 1

ORPort 7.8.9.10:1234 NoListen
ORPort 10.0.0.7:1234 NoAdvertise
ORPort [2345:bad:face::]:1234

Address 7.8.9.10
Address [2345:bad:face::]
OutboundBindAddress 10.0.0.7
OutboundBindAddress [2345:bad:face::]

ServerTransportPlugin obfs4 exec /usr/bin/obfs4proxy
ServerTransportListenAddr obfs4 10.0.0.7:4321

ExtORPort auto

With this config, I indeed am able to connect to the bridge using the "obfs4 7.8.9.10:4321 <...>" bridge line, 

but is this line also communicated like that by the bridge distributor, or do I need to adapt the above config to ensure proper distribution?

Thanks & regards, C.
