We have a office in US and one in India. We have a IPsec site to site vpn configured and individual Dial UP VPN's for India and US. The problem arises when we dial in to the indian PIX and try to access the us network or vice versa.
I googled and found out that PIX does not route traffic back from the same interface it comes into the network or something like this.
Can somone throw more light on this and also suggest possible solutions.
I understand that one way of doing it is by using VPN concentrator.
Will a version upgrade help? We are presently using Cisco PIX Firewall Version 6.3(1).
