I currently have a PIX setup at SiteA and a 1720 router at SiteB. There is a LAN-to-LAN tunnel between the 2 sites. If I was to setup a second tunnel at SiteB terminating on the 1720 router, will it be possible to configure the tunnels so SiteA also has access to the customer VPN tunnel?
I would also want to have VPN tunnels that terminate at the PIX (SiteA) to also be accessible from SiteB.
Would it just be a case of configuring the crypto ACL's for the traffic?
have a look at the following link will be very usefull
