Can't connect IOS to openvpn server on port 443

Posted: Mon Oct 23, 2017 2:39 am
by NasKar
I'm running an openvpn server on pfsense 2.4.0. On port 443 to get around hotels blocking my connections. I tried a server with TCP but get a tcp packet size error. So I'm trying UDP instead and can't connect either. Here is my openvpn log from pfsense set to verbosity 11

UDP port 443 has nothing to do with HTTPS and will probably be blocked.
(Your log above appears to confirm that it is blocked)

TCP port 443 should work well, what is the error you get.

The setup that the logs are from is from my cell phone connecting with the cellular service using port 443 UDP. So if the logs say it's blocked it's probably a problem with my firewall rules. Will have to redo the server/client when I get home to give you the exact error message but if was something like "TCP packet size error".

Sounds like compression .. make sure the setting for --comp-lzo matches both sides.

both are using the same compression comp-lzo adaptive as far as I can tell.
Still getting tpc_size_error

That could be a network error but ..

Please try with these settings in both server and client config:

Code: Select all

comp-lzo no
compress
which turns off all compression.

I have just tested with --comp-lzo adaptive and --proto tcp and found no errors.

I notice this in your log:

So you are on your local LAN trying to connect directly to your server ..

which is a puzzle ..

I need to see your complete server log at --verb 4

Your comment got me thinking. 192.168.5.80 is my nextcloud server which is on port 443. I have a Host Override in my DNS Resolver within PfSense that points my dynamic DNS to the IP of my nextcloud server. This allows me to access the nexcloud server with the ddns address on my local computer so links have the ddns address and not the local IP.

I have a second OPENVPN server on port 1195 UDP that works fine on my PFSense box. May have switch between the TCP 443 and UDP 1195 server in the logs I posted, hard to remember.

I tried to connect to TCP port 443 on my iPhone at 12PM today. Here is the iPhone log. I will have to wait till I get home to get you the complete server log at verb4.

 Here is the server log, 192.168.5.30 is my main computer on the LAN

192.168 again .. I think you have something interfering, like the pfSense router.

Unless the server and client are on the same LAN, connecting to 192.168.x.x is basically invalid ..

I logged onto the VPN from my iPhone on the cellular network with wifi turned off. Then got on my main computer on the 192.168.5.30 network to access the server log. If I have the IPhone wifi turned on then they would be on the same LAN 192.168.5.x. My guess from your help so far is it's a problem from my nextcloud server on port 443 causing a problem. I'll try to turn it off and see what happens.

I think I found part of the problem. I had port 443 forwarded to the 192.168.5.80 (nextcloud server) in pfsense. I removed it and added port-share 192.168.5.80 443 to the server config per this link https://doc.pfsense.org/index.php/Shari ... Web_Server. I'm now able to connect and view pages but the progress bar stops in the middle. It seem like there is still some issue. TinCan Tech I hope you won't mind looking at my new log files to troubleshoot for me.
