how to add vlan subnet in existing easyVPN setup

I am using EasyVPN:

Head Office(ASA 5510 with public ip) connected to SiteOffice(Cisco Router 2810 with PPPoE)
Head Office network: 192.168.2.0/24
Site Office network: 192.168.1.0/24
Everything is working fine.

Now I have another VLAN subnet(172.16.1.0/24), how I can add this network with existing easyVPN setup?

thanks

Hi,

      Yes, you can add Multiple Subnets to an Easy VPN inside interface.

Multiple Subnet Support
For situations in which you have multiple subnets connected to an Easy VPN inside interface, you can optionally include these subnets in the Easy VPN tunnel. First, you must specify the subnets that should be included by defining them in an ACL. To configure an ACL, see "Access control lists, configuring" in the "Additional References" section. Next, you have to use the acl command after the crypto ipsec client ezvpn (global) command to link your ACL to the Easy VPN configuration. Easy VPN Remote will automatically create the IPsec SAs for each subnet that is defined in the ACL as well as for the subnets that are defined on the Easy VPN inside interface.

Note:
Multiple subnets are not supported in client mode.

Note:
This functionality is supported only when the Cisco Easy VPN server and the Cisco Easy VPN client have the same type of Easy VPN configuration. In other words, both must use a Legacy Easy VPN configuration, or both must use a DVTI configuration.

let me know any config help need.

with router its working all vlans, only for vpn, look already network(192.168.2.0/24) and network(192.168.1.0/24) communicating with vpn, now i want to have access for all three networks via vpn.

with router my all vlans working fine, but i dont want to give access to vpn for all these.
only three networks(192.168.1.0/24, 192.168.2.0/24, 172.16.1.0/24) should work with VPN as two of them already working fine.
should i have to make changes on remote router also or only ASA change is enough?
and what will be the changes?

thanks
again comming to your  Questuion " Now I have another VLAN subnet(172.16.1.0/24), how I can add this network with existing easyVPN setup?"
where is this subnet   ? is it behind the  ASA  or  behind the ROuter .

since its a site to site vpn you have to do the chnages on  both side .
dear anoop,
all vlans behind router, and there is static router on router for one remote network(192.168.1.0/24) to ASA, and VPN is from ASA-to-Remote Router.

2nd, its not site to site VPN, its just easyVPN(remote access vpn).
 i think LIBI has a point that on remote side no need any change as it will automatically add once it will be in ACL on ASA.
but still me not clear how to this all.

thanks

dear Libi,

do i really need any static route in branch office.
1)- once you have ezvpn then it will not work automatically ?

2)- do i need to configure interface on ASA with ip 172.16.1.0/24 subnet as it has one ip already with 192.168.2.0/24 subnet

Please can you help me to make sure any changes in branch router first, then on head office

thanks
