iOS: Can't Connect to RDP or SSH

[chairmanmao]

I have an OpenVPN server which allows me to access my home LAN remotely using the Windows OpenVPN client. In Windows I can SSH through the OpenVPN server into devices on the back end of the OpenVPN server. I can also RDP, too.

However, neither of those things work from within iOS on my iPhone using either various SSH-capable terminal apps or the RDP app (I'm using the iOS OpenVPN app to access the VPN). Yet I can, under iOS, ping all the systems I should be able to access, either by IP address or host name (i.e., DNS resolution for the LAN domain appears to be working).

I'm at a loss to figure out what I'm doing wrong and would appreciate some advice. Here's my server.conf file:

Figured out the issue. On your iPhone or iPad go to settings under the OpenVPN app and click on all compression and set the to full. Then try to reconnect to the vpn. That should fix the issue.
