Dear,

I am facing Some Issue With Remote VPN

Issue is that i have Created Seperate Group for each user and allocated Seperate Single IP for each User.  Some time users connect to remote vpn but when they Disconnect their session remains in show Cisco crypto isakmp peers and their single IP is also allocated when i see using show local ip pool command.  So same user cannot connect again until i clear crypto session for that user.

Please Suggest..

Regards

Jawad

Dear It cisco 2811 Router and On client End its Cisco VPN Client Software and some other clients are using vpnc in Ubuntu.

I have Created Users As follows.

aaa authorization network ABC local

crypto isakmp policy 10

encr 3des

authentication pre-share

group 2

lifetime 28800

ip local pool ABC-POOL 192.168.1.200

crypto isakmp client configuration group ABC

key abc

pool ABC-POOL

save-password

crypto isakmp profile ABC-CM

   match identity group ABC

   isakmp authorization list ABC

   client configuration address respond

crypto dynamic-map DYNMAP 1

set transform-set VPNTRANSFORM

reverse-route

crypto ipsec transform-set VPNTRANSFORM esp-3des esp-sha-hmac

crypto map CLIENTMAP isakmp authorization list ABC

crypto map CLIENTMAP client configuration address respond

crypto map CLIENTMAP 10 ipsec-isakmp dynamic DYNMAP

Now With These Settings Clients gets connected,  but sometime clients dont Disconnect their Session and shutdown their pc, due to which Seesion is not ended in Router.

when i usse show crypto isakmp peer

Subject User is till Active

and then i use

show ip local pool command

his ip is also in used and as mentioned above in local ip pool i have given him single IP.

So at the same time he tried to connect he fials because his session is still active in router.

and i recieve following error

deleting SA reason "Fail to allocate ip address" state (R) MM_NO_STATE

When i cleir his session he successfully connects.

Please advice
