Cisco VPN distant monte mais impossible de pinger quoi que ce soit

Bonjour à tous,

je fais appel à vous car je viens de configurer un remote vpn sur un routeur cisco 1800 mais je rencontre un soucis:

La connexion sur ce denier depuis un poste Windows exécutant le client vpn cisco se fait bien mais une fois connecté il mais impossible de pinger ou contacter quoi que ce soit sur le réseaux distant.

Mon client vpn se connecte bien et récupère une adresse dans le pool 192.168.4.X mais avec une passerelle en 192.168.4.1 ????

Quelqu'un aurait il une idée du pourquoi je n'arrive pas à communiquer avec n'importe quelle machines du réseaux distant malgré le client connecté ?

Merci beaucoup

voici la config utilisé:
