ABSTRACT:
A method (300;400) and system (100) for transmitting information across a firewall (130b) between multiple endpoints (120) and gateways (135), in a resource management environment (such as the TME) having characteristics that are firewall-incompatible. A gateway proxy (125g) and an endpoint proxy (125e) are associated with the endpoints and the gateways, respectively. The two proxies are connected to each other by means of a pass through communication tunnel crossing the firewall, which tunnel is secured by mutual authentication of the gateway proxy and the endpoint proxy at its ends. Each endpoint and each gateway is tricked into communication only with the respective proxy. Particularly, a listening port is allocated on the endpoint proxy on behalf of each endpoint, so that the corresponding gateway will open a connection back to the endpoint proxy on the listening port for transmitting any packet to the endpoint. A table (230) stored on the endpoint proxy associates each listening port with the corresponding endpoint for managing the routing of the packets.
