Abstract
There are provided systems and methods for symmetric bi-directional routing in multi-homed IP networks which includes sending an IP packet having a source address from a first host and substituting the source address with an exterior routing address by a first network address translation gateway or firewall of the first host using conditional substitution. The IP packet, with the exterior routing address, is optionally routed via intermediate networks and firewalls and received by a first gateway or firewall of a second host. The second host responds to the first host along a route which traverses the same set of firewall gateways as the initial IP packet by using the exterior routing address as a destination address. The exterior routing address is converted back to the source address by the first network address translation gateway of the first host.
