Hi, look at https://wiki.fd.io/view/VPP/NAT
And my 5 cents 😉: cat /etc/setup.gate set int ip address GigabitEthernet0/3/0 10.0.0.1/31 set int state GigabitEthernet0/3/0 up bfd udp session add interface GigabitEthernet0/3/0 local-addr 10.0.0.1 peer-addr 10.0.0.0 desired-min-tx 100000 required-min-rx 100000 detect-mult 3 set int ip address GigabitEthernet0/4/0 1.0.0.2/24 set int state GigabitEthernet0/4/0 up ip route add 10.0.0.0/8 via 10.0.0.0 GigabitEthernet0/3/0 ip route add 0.0.0.0/0 via 1.0.0.1 GigabitEthernet0/4/0 set interface nat44 in GigabitEthernet0/3/0 set interface nat44 out GigabitEthernet0/4/0 nat44 add address 1.0.0.10 - 1.0.0.25 ________________________________ От: vpp-dev@lists.fd.io <vpp-dev@lists.fd.io> от имени varban metodiev <varban.metod...@telco.com> Отправлено: 23 января 2020 г. 16:01 Кому: vpp-dev@lists.fd.io <vpp-dev@lists.fd.io> Тема: [vpp-dev] NAT overload example Dear VPP Team, I am struggling with a MASQUERADE-like source NAT configuration with the VPP. Right now, I have UDP traffic traversing two interfaces. After applying the following configuration, I do not see any translation happening on the source IP. Configuration snippet: set interface nat44 out data7 output-feature set interface nat44 in data6 nat44 add interface address data7 May you please advise what I am missing and if possible, can you help me with a complete working example? Kind regards, Varban
