dear all,
i have following network scenario.
***
I HAVE ONE LAYER-3 SWITCH.(SGE2000-CISCO SMALL BUSINESS).
I HAVE THREE WEB MANAGED SWITCH.(SRRW224G4-CISCO SMALL BUSINESS)

NOW, ALL WEB MANAGED SWITCHES ARE FIXED IN THREE DIFFERENT DEPARTMENT. & LAYER-3 SWITCH IS FIXED IN CENTRAL SERVER LOCATION.

IN L-3 SWITCH, I HAVE CREATED THREE DIFFERENT VLANS & GIVEN DIFFERENT SUBNET TO EACH VLAN.
NAMELY,
(DEFAULT VALAN ID -100 & SUBNET IP:192.168.100.1/24)
(FIRST VALAN ID -10 & SUBNET IP:192.168.10.1/24)
(SECOND VALAN ID -20 & SUBNET IP:192.168.20.1/24)
(THIRD VALAN ID -30 & SUBNET IP:192.168.30.1/24)

NOW,
EACH DEPARTMENT SWITCH ARE ATTACHED TO L-3 AS PER THE PARTICULAR VLAN SEGMENT.

ON L-3 SWITCH,
TWO SERVERS ARE ATTACHED ON DEFAULT VALAN WITH THE SAME CLASS IP & GATEWAY OF DEFAULT VLAN IP(i.e. 192.168.100.1)
IN THIS CASE ALL THE PC FROM DIFFERENT VLANS ARE ABLE TO PING THE SERVER DUE TO INTRAVLAN COMMUNICATION.

*******
PROBLEM:
I HAVE ALSO ATTACHE ONE NETGEAR BROAD BAND ROUTER IN DEFAULT VLAN OF THE L-3 SWITCH, WITH THE IP ADDRESS OF 192.168.100.20/24.
I AM NOT ABLE TO GIVE THE GATEWAY ADDRESS ON THE LAN SEGMENT OF THE ROUTER & HENCE INTRA-VLAN PCS ARE NOT ABLE TO PING THEM & NOT ABLE TO USE THE INTERNET.

******* NOW I HAVE MIKROTIK RB 493AH BOARD.
WITH THIS BOARD HOW CAN I RESOLVE MY PROBLE?
********* HOW INTRA-VLAN PCS ARE ABLE TO USE INTERNET?***********

ITS BEAT URGENT.
PLZ. REPLY ANY ONE WITH SOLUTION AS EARLY AS POSSIBLE

you should set default route of your L3 switch to 192.168.100.20, so that all external traffic go to your router

unfortunately, no need of RB at all =(

Hi all, chupaka, i have just similar scenario as described above just that in my own case, i have a mikrotik gatway connected to the layer 3 switch. and i created the same vlans on my layer 3 switch on the mikrotik router and set default route to one of the ips on the router. That works fine; users can do intervlan on switch and access internet via the router but once i enable hostsot on each of the vlans on mikrotik, most clients gets disconnected and find it difficult to get the hotspot login page and if it comes up they are unable to access the internet. Local traffic still goes on smoothly though.

que: How do i make my hotspot work fine in this instance?

ojeysky, try to set 'Address Pool' to 'none' in your Hotspot Profile

Thanks i tried that but no luck...but its seem to be working now...will observe it for some time. What i did differently now was to change the default VLAN of my hp procurve switches from 1 to a different one and then used the mikrotik ip address of that particular vlan as the default gateway for the switch.

Will come back if it stops working
