IOS 9.2.1 client is ignoring proto udp

Reported by: tafinho Owned by: Antonio
Priority: major Milestone:
Component: OpenVPN Connect Version: 1.0.7
Severity: Not set (select this one, unless your'e a OpenVPN developer) Keywords: IOS UDP TCP


The following connection setup (working ok on MACOS):

dev tun
script-security 3
proto udp

results on the following logs:

OpenVPN core 3.0.11 ios arm64 64-bit built on Apr 15 2016 14:13:50

Which seems to be ignoring the proto directive.

anything else on the "remote" line that you're not showing? If you have "tcp" there (remote x.x.x.x 1194 tcp) this will have precedence.

A complete config - without IP addresses, passwords, and keys, of course - would make this easier to comment on.

This is the whole config, minus the embedded certificate:

dev tun
script-security 3
proto udp
remote 1194
resolv-retry infinite
reneg-sec 0
cipher AES-256-CBC

Actually, it's exactly that.

If I add udp it starts doing UDP connection . Doesn't work anyway, due to timeout, but at least it starts doing something right.

remote 1194 udp

Thanks for testing. I think it should also do the right thing with "proto udp" and not having udp on the "remote" line - but I have no insight into the iOS code, so I'll just give this to James.

v1.2.6 has just been launched on AppStore?. Could you please test that version and re-open this bug if the problem is still there?
