2018-09-13NAT: TCP MSS clampingMatus Fabian1-0/+76
NAT plugin changes the MSS value in TCP SYN packets to avoid fragmentation. If the negotiated MSS value is greater than the configured value it is changed to the configured value. If the negotiated MSS value is smaller than the configured value it remains unchanged. Change-Id: Ic3c4f94a2f1b76e2bf79f50f3ad36a4097f3f188 Signed-off-by: Matus Fabian <matfabia@cisco.com>

2018-06-15NAT44: endpoint dependent mode (VPP-1273)Matus Fabian1-7/+32
To enable NAT plugin endpoint dependent mode add following to statrup config: nat { endpoint-dependent } Enable endpoint dependent filtering and mapping for all sessions. Move some existing functionality such as service load balancing, twice nat, out2in-only static mappings and unknown protocol dynamic translations, which use endpoint dependent lookup hash tables before. Basically split to vanilla NAT44 and extra features NAT44. Change-Id: I3925eb5ddcc8f1ec4cf6af4e2a618a7ec7aa9735 Signed-off-by: Matus Fabian <matfabia@cisco.com>
