how to ping server from client on windows 7/8?

Daimroc

I know that this is a problem of windows firewall configuration, but I can't be able to find a solution.

I have configurated the server and the client. The server has the IP 20.30.0.1 and the client 20.30.0.6. From the client, I try to ping the server, but I don't have any response.

If I disabled the firewall, I have response, so I know that the problem is the firewall configuration.

One of the solution is not apply the rules of the firewall to the adapter that I use for the VPN, but I would like to use another solution, because I would like to have activated the firewall in all the adapters.

how can I solve this problem?

Server config:

port 1194
proto udp
dev tun
dev-node OpenVPN
server 20.30.0.0 255.255.255.0

ca ca.crt
cert srvCoru01.crt
key srvCoru01.key 
dh dh2048-srvCoru01.pem
tls-auth ta-hmac-srvCoru01.key 0
ifconfig-pool-persist ipp.txt

cipher AES-256-CBC

push "route 192.168.1.0 255.255.255.0"

push "redirect-gateway def1" 
push "dhcp-option DNS 208.67.220.220"

keepalive 10 120
comp-lzo

persist-key
persist-tun
status openvpn-status.log
verb 3

Client config:

client
dev tun
dev-node TunnelTap
proto udp 

remote 192.168.1.16 1194

resolv-retry infinite
nobind
persist-key
persist-tun

ca ca.crt
cert agarcia.crt
key agarcia.key
tls-auth ta.key 1
ns-cert-type server

cipher AES-256-CBC

comp-lzo
verb 3
explicit-exit-notify 2
ping 10
ping-restart 60

route-method exe
route-delay 2

Thanks.

Thaks for your repply.

I have to disabled the server firewall, the client firewall I have not needed to touch.

I think that the problem is that the incomming rules are configurated correcly, beacuse when I start openvpn.exe the first time, the firewall asks me if I want to allow, and I select private and public and allow all. So in theory the firewall allow all the traffic that going to the openpvn.exe application.

So if I am not wrong, the firewall wouldn't have to block the connections.

Also, if I go to the firewall configuration, I can see two rules for OpenVPN, one to allow all the traffic for all the ports thourgh the TCP and other rule for the UDP protocol. And in both cases, the openvpn.exe application has permission to use all the ports.

Thanks for the explain.

I try to add a new rule, for example open the port 1194 for the UDP protocol and allow all the connections, but the problem persists, so I gues that this is not the away too... The protocol that do I have to use is HTTP?

Could you say me how can I do it?

Thanks so much.

I have tried to open the port 80 and 443 and still the connections are blocked.

I don't understand, because by default in the ehternet interface works fine but for some reason in the TAP adapter block all.
