I can set up either a remote VPN Client 4.6 or a remote dynamic-ip router to connect to my router ( 2811 12.3(8)T6) with ipsec, but not both.
For the case of remote VPN Client, I specify the preshared key and remote group with "crypto isakmp client configuration group vpnclient" and "key myclientkey".
For the case of a remote dynamic-ip router, I specify the preshared key thru "crypto isakmp key mypeerkey 0.0.0.0 0.0.0.0 no-xauth".
My problem is "crypto isakmp key mypeerkey" overrides the key of the VPN client : I have to set VPN client to use the key "mypeerkey". This is not very bad, but then in this case I have to get rid of "no-xauth" because VPN Client wants xauth( am I wrong? ) . But without "no-xauth" my remote dynamic router fails connecting to.
My question is how I specify the key for the remote dynamic router separately from the key for the VPN Client ?
If the above is not possible ( I have to use same key ) then how I specify in which case "no-xauth" will apply ?
Or do I do something wrong basically then which is the correct one ?
