Multiple VLANs Router mode?

Hi,

I'm assisting a friend to decide on a VSAT for his office in Mexico and we have a question about the iDirect router. He needs to seperate traffic between his own office and two other business wanting to share the same VSAT.

I read it supports multiple VLANs - but we wanted to know, if it acts as a switch in this case (which means no local DHCP, NAT or RIP support), or it is still a router with all the services.

If it is still a router - does it mean it have seperate routing tables per VLAN? 'cause if not - does the router routes traffic between different VLANs (and then it doesn't ansewr the seperation need).

Thanks for all of you in this wonderful site.

The iDirect VLAN feature is designed to allow multiple sites on an iDirect-enabled network to operate as a VLAN, so they can pass traffic between themselves.

The VLAN feature does not apply to multiple subnets or routes at the remote site.  You can use a standalone router or layer 3 switch to create multiple (private IP)network segments behind the iDirect modem/router.

The iDirect modem/router does not route between the switch ports on the 5100 or provide multi-LAN routing between multiple networks on the same LAN.   (Unless they've added something I don't know about). 

iDirect also has a device called the MUSiC box (multi-user summing chassis or something like that).  I think they still sell this.  It used to list for about $6200.  It allowed multiple iDirect modem/routers to share a single ODU (dish/buc/lnb), so that each customer had his own modem/router and billable account.

Hope this helps,

Pat

Thanks for the reply man.
How the VLAN mode is related with Routing capabilities of the 5100?
Can I set local DHCP for example per VLAN-port in the 5100 - with different pools. Does the 5100 hold a routing table per VLAN?
If I still want NAT - do I need to user external device - or can I set NAT per VLAN-port?

I'm not sure you understood me.  The 5100 does not route between its switch ports. 

The iDirect Hub can be configured to create a VLAN consisting of multiple remote sites. 

Your network operator can configure NAT and DHCP on your 5100, but there is only 1 (one) routed IP network coming out of the 5100.  You cannot configure DHCP/NAT on each of the switch ports. 

Most customers elect to use a local server or gateway/router to perform NAT/DHCP so that they have local control and don't have to go to the network operator for any configuration changes.
