VPN Sample Configuration with NEM, EZ-IPSec & Internet Access
XSR(config)#ip local pool virtual_subnet 10.10.10.0 255.255.255.248
Configure AAA authentication by assigning a virtual subnet to the DEFAULT AAA group,
associate it with DNS and WINs servers, and add two AAA users with passwords.
When a remote XSR tunnels into the local XSR, it will be assigned these DNS, WINS and PPTP
values and be assigned dynamically to the IP pool virtual_subnet. Be aware that users not added to
a specified group will automatically be assigned to the DEFAULT group and groups must be
created before users can be added to them. Remember to create the same users and passwords on
the remote XSRs.
XSR(ip-local-pool)#aaa group DEFAULT
XSR(aaa-group)#ip pool virtual_subnet
Configure DNS and WINS parameters:
XSR(aaa-group)#dns server primary 172.16.10.10
XSR(aaa-group)#dns server secondary 172.16.10.11
XSR(aaa-group)#wins server primary 172.16.10.10
XSR(aaa-group)#wins server secondary 172.16.10.11
Create user(s), specify an IP from virtual subnet, and assign a password:
XSR(config)#aaa user nem-test
XSR(config)#password welcome
XSR(config)#aaa user jeffb
XSR(config)#password welcome
Check to make sure the transforms and proposals were created properly:
XSR#show crypto ipsec transform-set

XSR(config)#config-mode gateway
XSR(config)#exchange-mode aggressive
XSR(config)#proposal ez-ike-3des-sha-psk ez-ike-3des-md5-psk
Create the ACL for trusted subnet of 1100(s) and virtual subnet of XSR:
XSR(config)#access-list 101 permit ip any 10.11.11.0 0.0.0.255
