Dear All,
First of all, i want to apologize for my poor level of English.
I'm using OpenWRT on Linksys WRT-3200ACM router. I tried to configure OpenVPN and have an issue with clients. I followed one of the different howto findable on the web.
Connexion seems to be ok, but i don't have any access to my LAN ressources even after configuring specific rules on firewall. A continuous ping shows that immediatlly after connexion two first ICMP packets are answered. but after no more communication.
Of course i checked on client side and disabled all firewall which could cause this issue. I'm running out of idea 
I hope you may help. I'm of course available for any information needed
Best regards.
