I was to follow this cisco example of configuring a Lan-to-Lan VPN:
hostname(config)# interface ethernet0
hostname(config-if)# ip address 10.10.4.100 255.255.0.0
hostname(config-if)# no shutdown
hostname(config)# isakmp policy 1 authentication pre-share
hostname(config)# isakmp policy 1 encryption 3des
hostname(config)# isakmp policy 1 hash sha
hostname(config)# isakmp policy 1 group 2
hostname(config)# isakmp policy 1 lifetime 43200
hostname(config)# isakmp enable outside
hostname(config)# crypto ipsec transform set FirstSet esp-3des esp-md5-hmac
hostname(config)# access-list l2l_list extended permit ip 192.168.0.0 255.255.0.0
150.150.0.0 255.255.0.0
hostname(config)# tunnel-group 10.10.4.108 type ipsec-l2l
hostname(config)# tunnel-group 10.10.4.108 ipsec-attributes
hostname(config-ipsec)# pre-shared-key xxx
hostname(config)# crypto map abcmap 1 match address l2l_list
hostname(config)# crypto map abcmap 1 set peer 10.10.4.108
hostname(config)# crypto map abcmap 1 set transform-set FirstSet
hostname(config)# crypto map abcmap interface outside
hostname(config)# write memory
If I later on need to set up a new tunnel group to, let's say a dmz on the one of the hosts, do I need to redo the isakmp policy part for every new connection or is adding a new tunnel group and a new access-list enough?
