Some ports blocked

[henck@…]

Are some outgoing ports blocked? I'm unable to connect to non-443/80 ports in my testing. I can't find any relevant documentation

[randy@…]

we do not believe we are blocking outbound ports; though we could be wrong. can you give more specifics so we can test? thanks.

Which wireless (or wired) network do you use? What are your IP addresses?
Thanks

I am using IETF-Hotel - For example: nc 8.8.8.8 53 fails, while it succeeds
on the Marriott network

ifconfig output:
inet6 fe80::4b1:ce43:d406:b3fa%en0 prefixlen 64 secured scopeid 0x8
inet6 2001:67c:1232:144:1421:7f12:2c3e:d3d1 prefixlen 64 autoconf secured
inet6 2001:67c:1232:144:25b7:7545:2846:e4a5 prefixlen 64 autoconf temporary
inet 169.254.236.148 netmask 0xffff0000 broadcast 169.254.255.255

Yes, that is „our“ network.

But you appear not to have a „useful“ global
IPv4 address (only link local).

Can you please check whether DHCPv4
is turned on?

I will also attempt to check our end for
potential problems when interacting with
your device.

Should work better now. Please retry!

[henck@…]

Works thanks! Got a routable ipv4 address and connections to ipv4 endpoints
are working.

I believe this is a duplicate of the issue in ticket #1246 - can you test again
this morning and report back?

Thanks -

Lucy

[llynch@…]

ignore - wrong ticket - #1248 may be a duplicate of this!
