I'm just going to take a stab at this and hopfully be of some help.
If your firewall has a static route setup for the 192.168.1.0/255.255.255.0 network using your 1841 as the gateway, you might want to try editing that route to be 192.168.0.0/255.255.0.0 OR adding another static route.

Anybody?

What is the model of router do you have? If you are getting to the router that means the switch is working correctly. Problem seems to be at the router.
Thanks

The router is Cisco 1841, I know this is strange because HOSTs in VLAN1 isworking fine, have internet and everything.
VLAN2 hosts can ping .19 but don't have the Internet...
Also I have firewall after router, could firewall block my VLAN2 because it has different IP range?
Also note that my router has no DHCP anabled...... maybe I need to add some NATing?

Problem for sure is with router and probably with NAT's ACL or ACL on LAN interface. Paste "sh access-list" and "sh ip route" and part of NAT configuration

Ok here is my routing list, I dont have any NAT config or any ACL's
the 42.0 route is for another network from other place which is working fine also.....
192.168.1.5 is my firewall ....
I added 192.168.2.0 to the RIP networks but didnt help

WORKING, I added new route looks like 192.168.2.0/255.255.255.0 to 192.168.1.19 and it is working !!!!!
