IPSec Site to Site Connection
Hi,
How to connect branch office which is the firewall is behind router?
Branch office WAN using local ip, while router using public ip
Hello!
1. You must configure NAT to change incoming public ip to your firewalls ip which will be responsible for IPSec connection.
2. On the other Site while configuring you will have to enable NAT Traversal (which will tell to the firewall that you will be connecting to the NAT ed private ip address).
3. Don't use AH (authentication header) in this use case. Because of AH encrypts whole ip packet in tunnel mode it wont work.
