I have one IP xx.xx.xx.122/29 on eth1.
how to transfer internet to eth6 with IP address xx.xx.xx.123/29 so I can put some server there?

Im going to assume you want the routerOS to assign public ip to your server.
What you do is create a bridge/switch between your server port and eth1. > IMPOSSIBLE. I have pppoe server running. ports 3 and 4 are in bridge and using one of /29 IP from eth1.
create a dhcp server that assigns that 1 single ip address only to eth6 and do not give eth6 that ip address, instead assign the ip address on eth1 to the bridge.
Than your server should now be directly connected to the internet with a public ip. If you want to use firewall from routerboard on traffic than make sure you used bridge.
