openVPN connected but can't ping

Question

I'm currently installing an OpenVPN clent+server to have a remote acces to my server files. I've set up both side, generated the keys and now my client can be connected (with the green icon). Once i'm in the VPN network, I can't do anything. It's impossible for me to ping 10.8.0.1 (the VPN server adress) or to connect to my remote files. The strangest things here is that everything was working last week, i don't know what i've broke haha. My server runs under windows 2012r2 and all my clients under windows 10. Here is my configuration file : -client:

client
dev tun
;dev-node MyTap
;proto tcp
proto udp
remote WWW.XXX.YYY.ZZZ 27234 #(IPv4 adress)
;remote 192.168.1.10 27234
;remote-random
resolv-retry infinite
nobind
;user nobody
;group nobody
persist-key
persist-tun
;http-proxy-retry # retry on connection failures
;http-proxy [proxy server] [proxy port #]

ca      ca.crt
cert    client1.crt
key     client1.key
remote-cert-tls server
cipher AES-256-CBC

;mute 20

and for the server side:

;local 192.168.1.10
port 27234
;proto tcp
proto udp
;dev tap
dev tun
;dev-node MyTap
ca      "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\ca.crt"

Do you know why can't I access my files ? When i ping i don't have any respond, but wireshark show me that the server get the ping, but don't answer to it. Any help is welcome, have a good day. SeedBarrett

Answer 1

ok after 3 longs day i have finaly discovered the truth : my server's firewall blocked my port on the output. That's why i could be connected but i hadn't any ping or anything. I hope it will help someone else. TRIPLE CHECK YOUR FIREWALL (double checking wasn't enought for me haha)
