Hi,
You can create a IPSEC/GRE tunnel b/w them... The following is example for GRE..
Site A
---------------
interface Tunnel1
description VPN Tunnel to Site B.
ip address 192.168.201.1 255.255.255.252 (use any unused ip with /30 mask)
tunnel source DialerXXXX
tunnel destination 80.37.x.x
ip route 172.26.0.x 255.255.255.0 Tunnel1
ip route 0.0.0.0 0.0.0.0 Dialerxx
ip route 80.37.x.x 255.255.255.255 Dialerxxx
Site B
---------------
interface Tunnel1
description VPN Tunnel to Site A.
ip address 192.168.201.2 255.255.255.252 (use any unused ip with /30 mask)
tunnel source DialerXXXX
tunnel destination 80.38.x.x
ip route 192.168.1.x 255.255.255.0 Tunnel1
ip route 0.0.0.0 0.0.0.0 Dialerxx
ip route 80.38.x.x 255.255.255.255 Dialerxxx
You need to configure the dialer setting for ADSL.
