I am using a RB411UAHR (ROS version 4.13). I have an IPsec tunnel configured to my Strongswan server.
All the communications are working perfectly well between both site but now I want to forward DHCP requests comming from the ethernet side to a DHCP server on the other side of my IPSec tunnel and it doesn’t work.
We sniffed the packets on the PPP interface side and we saw that DHCP requests are fowarded to the right server but the source adress is a public IP address on the internet side.
Is anybody would know how we could change the source address in the DHCP request fowarded thorught my IPsec tunnel
Thanks
