 Subject:  multiple subnets on one monowall
 Date:  Fri, 4 Nov 2005 02:32:40 +0100
Hi all

 

First let me tell you how my network is

 

I have multiple networks like

 

192.168.1.0 / 24 gw 192.168.1.1 vlan 101

192.168.2.0 / 24 gw 192.168.2.1 vlan 102

192.168.3.0 / 24 gw 192.168.3.1 vlan 103

Etc etc etc 

Up to about 

192.168.15.0 / 24 gw 192.168.15.1 vlan 115

 

These are running on their own vlans connected to a bunch of HP2650 layer 2
managed switches, which all are connected to a Netgear GSM7312 Layer 3
switch, that is our default gateway for all these subnets

 

From the layer 3 switch, the traffic runs into a cisco pic 506 and then onto
our cisco 4000 router which runs our internet, and everything is fine

 


shaper option on our entire network

 

The monowall has to Ethernet cards in, one for lan which is 192.168.1.2 / 24
gateway 192.168.1.1

The other for wan is 80.164.175.xxx / 28 gateway 80.164.175.xxx

 

I have in the monowall created a lot of static routes, one from every subnet
like

 

192.168.1.0 /24 gateway 192.168.1.1

192.168.2.0 /24 gateway 192.168.1.1

192.168.3.0 / 24 gateway 192.168.1.1

 

And so on

 

But I cant get this to work

 


192.168.1.2 as my default gateway, I can get thru to the internet, though
the monowall, and everything is fine, I can ping other machines on other
vlans, example 192.168.2.50, so that is also working.

 


define the next hop address in the layer 3 switch to be 192.168.1.2 I cant
get out.

 


192.168.3.50 ip with 192.168.3.1 for gateway (same layer 3 switch), with
next hop address 192.168.1.2, NO GO

 

I hope you can understand what it is I want to do?

 

Just to clarify, in my layer 3 switch I define the next hop address, which
is normally my pix 192.168.1.7 and this is working flawlessly, but when I


 

From the monowall I can ping the internet, and also machines on different
vlans, so it does have some kind of contact with them.

 

Also I have experienced, that every time I make a change I the monowall, and
press apply, I lose the monowall, stops responding to ping, and I then have
to reboot the monowall, using option 5 in the menu interface, when rebooted
it have accepted the changes, but still, I think its odd that it behaves
like this.

 



 

Hope that any one can help me, figure out what is wrong, or maybe just
clarify, whether the monowall can handle all these subnets?
