Passthrough of WAN address to ethernet port (SG310) possible?

Russ McGinley

Hello.  I have a requirement where I need to set up another device on one of the IP addresses issued by my ISP.  Currently my connection comes in via fiber and is terminated at the SG310.  I can terminate it at a switch and pass ethernet off to the two devices, but figured I'd ask here if it's possible (I opened a support ticket and the guy that I spoke with questioned why I needed to do that and tried to tell me that I didn't need to do it..  never answered my question).  

 

So, basically, I have a /29 address range, and I want to pass one address off to the other device.  I was wondering if it's possible to create a bridge or a passthrough to one of the unused ethernet ports and have that traffic be unfiltered.  I don't want to do a NAT.

    Hi Russ,  I hope everything is going well for you now.  I have fiber coming into to a Cisco Router with a /27 address range and I have 2 devices that need a pass-through. I am making this way harder than it should be.

    All you did was assign a switch a unused IP then connected your firewall to it, then the devices that need pass-through you connected to the switch right?

    What I ended up doing was plugging the fiber into an unused port on my 5412zl, then created an unrouted VLAN including the fiber port and two ethernet ports, then plugged one ethernet into the SG310 and one in the other device.
