Methods and systems are disclosed herein for providing a universal PCIe port. In one example, the same port is configured to accept a PCIe connection as a host or an endpoint symmetrically. Downstream transactions towards an endpoint can be intercepted and a virtual address in the downstream transaction can be translated to a local address using a mapping. The downstream transactions can be forwarded to the endpoint using the local address instead of the virtual address. For endpoints that share the same local address with multiple hosts, a reverse lookup may be provided to determine which one of the hosts a local address corresponds when forwarding upstream transactions. PCIe over Ethernet is provided as one embodiment for allowing remote PCIe endpoints to be associated with a local host transparently.
