no traffic passing through VPN between R 877 and remote Cisco VPN client
Hi there, I need help trying to solve this problem up. I have no more ideas...
I have a vpn established between my router 877 and an XP in a remote network behind nat router, and running cisco vpn client software (v4.7.00.0533). Once vpn is established, I am not able to even ping from remote client any host inside my lan.
Lan: 192.168.100.0/24 vlan1 interface
Virtual Ip for remote user: 192.168.110.0-10
Pinging from remote host to local host:
If I sniff in local host, none packets are received.
If I sniff in remote host, UDPencap packets from its private Ip to my public IP are sent through real interface, so I beleive remote side configuration is well done. These udpencap packets should be nated and routed by remote router (common adsl router with no outbound restrictions) and processed by my local-vpn-gw.
If I sniff remotely in the virtual cisco vpn interface I can see icmp packets from virtual IP to private IP of my local host.
I understand that my router is detecting nat usage automatically, so shouldnt be an issue related to nat-traversal.
I have tryied to guess at least if traffic is reaching my local gw. How can I see if this udpencp packets comming from my remote vpn client are reaching at least my vpn gw?
Please, I would much apreciate some help on this....
Re: no traffic passing through VPN between R 877 and remote Cisc
All IP traffic passing through the interface is evaluated against the applied crypto map set. If a crypto map entry sees outbound IP traffic that should be protected and the crypto map specifies the use of IKE, a security association is negotiated with the remote peer according to the parameters included in the crypto map entry.
