Good afternoon everyone,
I'am a newbie at configuring cisco routers, I had made a few month ago a VPN tunnel between 2 sites. Site A had the VPN server on a cisco SR520-ADSL-K9 network is 192.168.1.0 (public IP is 80.11.82.100 (not real).
Site B is the VPN client and uses the same cisco equipment, the VPN link was made using CCA (vpn remote) and was working well... until some power failures made the Site B SR520 not working at all (ethernet interfaces were down), network on site B is 192.168.2.0
I then completly reset Site B router and tried to rebuild the original configuration (tried because, I FAILED !).
I noticed that I have the following redundant message in console :
*Aug 8 12:43:52.971: %CRYPTO-6-EZVPN_CONNECTION_DOWN: (Client) User= Group=EZVPN_GROUP_1 Server_public_addr=80.11.82.100
*Aug 8 12:44:04.924: %CRYPTO-6-IKMP_NOT_ENCRYPTED: IKE packet from 80.11.82.100 was not encrypted and it should've been.
Some Cisco docs says there is something to do with ACLs but because I am newbie ... I don't know what exactly and which commands should I enter :-( (note that I have not set up the firewall to be sure the problem was not linked to it)
Below is my Site B SR520 running-configuration, hope it might help. I will be very gratefull to the one who can help me finding what is wrong and how to solve it (I have to fix this within 2 days, because my customer production Site (B) has no access to his data server located on site A.
Many Thanks in advance !
