Seeking suggestions for a WG port to use with restrictive public wifi networks

Seeking suggestions for a WG port to use with restrictive public wifi networks

[John]

Use case: WG VPN server (linux) and iOS clients (I mention that
because the solution need to just-work with the iOS WG client without
extra steps for ease).

Goal: identify a port on which to run WG that has a good chance of
being open to clients on both LTE and public WiFi networks.

I currently run OpenVPN on 80/tcp which works for the vast majority of
networks.  I'd like to switch over to WG.

I found that port 123 is not very compatible with the public networks
I tend to use.  Port 53 seems to work on WiFi, but does not ork due to
Verizon actively blocking traffic on it.  I tried a few higher numbers
including 51820 and 41185 but they seem to be blocked.  I also tried a
few standard service ports including: 80, 443, and 1194 but all of
which failed to connect.

Should I stick with the "standard" udp service ports for my
trial-and-error based approach?  Wikipedia has an article that lists
many of these (List_of_TCP_and_UDP_port_numbers).  Any suggestions are
welcomed.

Possibly: UDP/500 (IPSec IKE) or UDP/4500 (IPSec NAT-T)

And also 4433 which is used by DTLS

Good call on these ports, Lonnie.  I am able use use either 500 or
4500 get WireGuard connectivity on my public WiFis.  I also tested
4433 and 1701 (suggested by others in reply to my query) but got a
mixed result with some networks allowing traffic on them and others
not.

Have you tried 1701/udp? That's the standard L2TP port - it's unlikely to
be particularly useful on networks which deliberate block VPN access, but
I've encountered a number of networks on which that port was usable, and
not much else.

Cheers,
Steve
