I’m glad that everything worked out for you, and I am glad that I could help. Take care bud.

Just an update to this, the static route worked just fine. I’m annoyed at the help section on the RV042 for indicating I couldn’t use a static route with dhcp, but glad that helpful people (like Santucci44) are around to give some proper information

Thanks again for the help,
Lordhowe

Ahhh…I see it now, thanks! In the instructions on the actual router, it says explicitly “You can not create static routes if you have dhcp enabled!” so I’m not sure why the disconnect with the manual :/

Anyway, I’ll give it a try in the morning and let you know how it goes, thanks again!

Lordhowe,

Yes you can. I’m telling you to put in a static route to another network subnet which has nothing to do with the dhcp being enabled or disabled. Please review page 18 of your manual, which is advanced routing section. But you must make sure that you give your switch a routed port and ip address of the 192.168.101.x subnet like mentioned in my other instructions. I have setup clients like this before and it works with 10 different subnets/vlans. you could also have multiple dhcp servers running, one on the switch and one on the linksys. Just make sure you created the vlan interfaces.

Hi Santucci44,

Thanks for the reply! There is one issue i see with your answer though, and that is that the RV042 won’t allow you to create static routes as long as dhcp is enabled. I don’t want to disable dhcp (mainly because I don’t want to have to create static ip’s for every device in our office), so, I’m still not sure how to proceed.

Thanks,
Lordhowe

You should have an Ethernet connection connected to one of the FA ports on the Cisco SGE2010P and the other end connected to your linksys lan port.

If you connected the patch cable to lets say fa 0/48 on the cisco switch, then you need to make sure you turn it into a routed switch port by initiating the ” No Switchport” command in interface configuration mode. Once you do that, you need to assign it an IP Address from the subnet of the Linksys Router which is your 192.168.101.X subnet. You’ll need to first find out which address aren’t in the dhcp pool, so when you look in your Linksys router, find out where the dhcp pool address start from and anything under the start number is all excluded from dhcp.

So, for kicks and giggles, lets say that you look inside your Linksys Router and it says that you allow 100 dhcp clients and the addresses start from 192.168.101.100, then 192.168.101.1 to 192.168.101.99 are all set aside for static addressing. Assuming this is the scenario, I would assign any number you have available to the FA 0/48 port. So, let’s again say that you have 192.168.101.10 available, go into your FA 0/48, and put in ” IP Address 192.168.101.10 255.255.255.0″ Make sure you do a No Shut.

then on your Linksys, put a static route for the other subnet by typing, 192.168.104.0 255.255.255.0 192.168.101.10.

On the cicso switch, make sure you use a default static route to get out to the internet by using 0.0.0.0 0.0.0.0 192.168.101.253

I don’t think I forgot anything; but hit me up if this doesn’t work.
