I have a doubt.
One of my customer is asking me to configure ipsec remote access vpn with cisco asa 8.0 ios and cisoc 877 router.
The requirement is that the client should get the ip address through HO's DHCP server.
I doubt whether this is possible or not.
Any ideas greatly appreciated.
the customer wants to know both the things...
Through asa we can provide the ip address through the dhcp server using the link which you gave.
but the customer also wants to know that whether the same this is possible on a router also instead of cisco asa at HO.
cisco 877 ---> ipsec vpn----> cisco 2800 ----> dhcp server.
If a client is on the LAN of the 877 and requires an IP address from the HO - then should work into the IPSEC VPN.
If you are asking if the 877 is configured for VPN client access, and you want to have an IP address assigned to the VPN client,
connected to the 877 from the HO over an IPSEC VPN, then I cannot see why you would want this.
As long as there is IP network connectivity between the 877 and the HO DHCP server it should work.
What the IP helper-address bascially does, is forward a UDP broadcasts. So when the DHCP server recevies the DHCP request,
from the router it will reply with an IP offer but send it directly to the routers LAN IP adddress. Since this is a unicast traffic flow so it should work.
