Hi group,

    I catch a problem when connecting to VPN Server. I configure Easy VPN
Server on a router 2610 with IOS "c2600-ik9o3s3-mz.123-15b.bin". But when I
connect from VPN Client (ver 4.6), it always drop with the message "Error 412
: the remote peer is no longer responding". On the router, it shows up a
message "%CRYPTO-6-IKMP_MODE_FAILURE: Processing of Aggressive mode failed
with peer at 192.168.1.25"
    I turned off the firewall on my PC but it's still unable to connect. I
post here the configuration of my router. Does anyone know how to fix this
problem?

Thanks
Hai Minh
