RB 750G as a layer3 switch with DHCP relay

Hey guys, i'm having a hell of a time getting this setup correctly..... I want to setup my RB750G as a DHCP relay to my DHCP server..... Lets say the DHCP server is... 206.203.104.1/25 (i'm really a different public ip but for security I wont post any of the real addresses)

I want port 1 of the RB750G to be the "Wan" port so to speak... And all DHCP requests to go out that port.... I added an IP on port 1 206.203.104.2/25 and the Route comes up as reachable to the DHCP server... I can also ping it from the Tik....

Now if I wanted to switch ports 2-5 and have port 1 be the master all I need is something like this correct?

[admin@MikroTik] > /interface ethernet
[admin@MikroTik] /interface ethernet> print
Flags: X - disabled, R - running, S - slave

NAME MTU MAC-ADDRESS ARP MASTER-PORT SWITCH

0 R ether1 1500 00:0C:42:70:xx:xx enabled none switch1
1 RS ether2 1500 00:0C:42:70:xx:xx enabled ether1 switch1
2 RS ether3 1500 00:0C:42:70:xx:xx enabled ether1 switch1
3 S ether4 1500 00:0C:42:70:xx:xx enabled ether1 switch1
4 S ether5 1500 00:0C:42:70:xx:xx enabled ether1 switch1

Now everything that plugs into ports 2-5 should be switched with port 1 and any traffic or DHCP requests should also go out port 1?

Or is bridging a better option?
Thanks again for the help guys! I'm learning on the go here so take it easy on me :smiley:
