How to bridge wan port

hello support

how to bridge wan1 port to wan2 port?

thanks

Can you explain what you mean?

for example the ISP give /29 block of public ip so in wan1 will be the connection coming from isp then in wan3 i put another machine which required also a public ip

This can be accomplished using the drop-in mode functionality on the Balance 210 or above and would be on the LAN side not on a WAN port:
