> I just wish Signal was easier to get through a firewall. ... I couldn't even make messaging work through a firewall... That's really, really strange. I sit behind an IPv4 NATting router whose policy is "default REJECT unless the packet is related to a connection that conntrack knows about". [0] The device also runs UPnP, but Signal never attempts to forward any ports. Full disclosure: I have good IPv6 service, but textsecure-service-ca.whispersystems.org doesn't have any AAAA records, so I don't see what that would have to do with anything. My friends and I can use both Signal text and voice messaging without issue. Just what sort of obscenely restrictive firewall are you behind? [0] You know, a typical NAT firewall configuration.

> Just what sort of obscenely restrictive firewall are you behind? Many companies block outbound on non-well known ports, for various reasons. tcp/443 is almost always available though.

  > Many companies block outbound on non-well known ports... Mmmhmm. Yeah, I'm aware of that. :) However, click170 made no mention of a corporate firewall. He said: > I just wish Signal was easier to get through a firewall. Which is dramatically at odds with my and my friends experience with Signal; namely that it passes through firewalls with no configuration required. If he would have mentioned that it was a corporate firewall that he was trying to get through, I expect his comment would have been much less popular, and much less confusing. :)
