I work from home and often on the road. My home router is an Asus RT-66U and am using the latest "freshtomato" firmware. I have the supplied Openvpn server configured on the router using a routed/tun connection and self-signed tls certs. The connection works perfectly on EVERY wifi connection I have used it on, and connects almost instantly EXCEPT for the ONE that I *try* to use the most, that being one our local public library branches. Viewed from the user standpoint, the KUbuntu network manager openvpn connector simply times out after a long wait. I see the same issue on a windows 10 laptop and the community openvpn client. Since the logs on both Linux and windows really don't tell me anything, I fired up wireshark with a capture filter of "port 1194" and see the following:
Code: Select all

7 30.534615049 library_ip 59136 home_ip openvpn OpenVPN 56 MessageType: P_CONTROL_HARD_RESET_CLIENT_V2
The wireshark capture ends and about 15 seconds later, the windows client or linux client pops up a "connection timed out"... The fact that the openvpn connection works EVERYWHERE else besides the library tells me that *something* the library infrastructure is doing is screwing
up my vpn. Any ideas? I'm not really hep on openvpn issues but figured a wireshark capture shown to the right people might give me some
ammo to use with whatever the library calls its "IT department"...
Thanks in advance
