Two router cascade conundrum
Posted on 2006-04-09
I have two networks I wish to separate. Both need access to the internet.
Router A is a Linksys wrt54g connected to the internet via a (Alcatel) modem. LAN address 192.168.1.211 LAN IP range 192.168.1.x DHCP enabled. It gets its IP from the server using PPPOE.
Router B is an Alloy IP505DV connected via WAN port to a LAN port on A. WAN IP address is 192.168.1.202 Gateway 192.168.1.211 LAN IP range 192.168.0.x DHCP is disabled. Router is set to 'router' mode rather than 'gateway'. NAT disabled.
I have followed instructions from Alloy's very good telephone support and cross checked with various threads here and elsewhere, I have also rung them back to check that there is no setting on the IP505DV that I have missed. I am not considering ringing Linksys help as it is via a scripted person and has proved next to useless in the past.
This is the situation:
Router B can see the internet, pinging the gateway 192.168.1.211 fine, DNS 184.108.40.206 fine, proxy sever in China 220.127.116.11 fine via network diagnostics in the HTML interface.
PCs (XP PRO) connected to router B with IP addresses in the same range can ping the router 192.168.0.201, but cannot ping anything else. Gateway set to router B IP. DNS 18.104.22.168
** If I connect router B to router A via a LAN port on B, change the IP on the PC to be within the same range as router A and gateway to router A IP then all is fine and internet accessible.**
This is great apart form the fact that:
I want to separate the two networks. Computers connected to router A should not be able to see computers connected to router B.
As an added bonus I want computers connected to router B to be able to see computers connected to router A, if this is possible.
This is probably quite simple for anyone who understands what it is that routers *actually* do, but it has wasted a whole bunch of my time.
