Have an old cisco 800 Series router with 4 switchports and one Wan, can I route between VLANS on the switchports?

I've set up two of the LAN switchports to host two VLANs but I cannot get hosts on those respective ports to communicate with each other no matter.  Didn't know if this was a limitation of the router itself or what.  I can get this running on a switch with no problem, but not this device.  Any ideas?  Thanks.

That should not be limitation of router. I worked with 800 series and I did not have such issue.
Can you paste configuration?

Configuration seems to be OK.
ip routing is missing - but I think that is default on this routers, so it will not be shown in running config. You can check is ip routing  command present on router issuing #show running-config all.

Did you double check ip addresses and default gateway on hosts?
Can you ping your default gateway address from hosts?

I entered network parts of your config to Cisco 881 and intervlan traffic is OK.

In my case I had problem with one host - windows 7 - network location was set to public, and even from router I could not ping that host, although that host could ping router and all other hosts (maybe that is problem in your case).
When firewall is turned off on that host I could ping it, and everything worked fine, so ...

Double check ip addresses and default gateway on hosts.
Try to ping your default gateway address from hosts and ping hosts from router to check is ping from router to hosts is OK.
