Hi,

Run NAT plugin in endpoint-dependent mode (add following to startup config “nat 
{ endpoint-dependent }”), enable NAT feature “set interface nat44 in tap3 out 
GigabitEthernet4/0/0” and create static mapping “nat44 add static mapping tcp 
local 192.168.1.2 80 external GigabitEthernet4/0/0 80 out2in-only”.

NAT might be the right way to achieve this.

This is the command I used with iptables:
iptables -t nat -A eth0 -p tcp --dport 80 -j DNAT --to-destination 192.168.1.2

What is a similar command on VPP-NAT when I am trying to send port 80 traffic 
from main interface to tap-device:
main interface: GigabitEthernet4/0/0
tap id: 3 (tap3) with address 192.168.1.2 and host-if-name tapcap

Thanks
