Hello, just wanted to gather some information about sperating 2 networks using 1 WRT54G as a DSL router. This would be my setup: Code: DSL | WRT54G (Talisman or Alchemy) | | NetworkA NetworkB 192.168.1.0 192.168.2.0 I need access from NetworkA to several machines on NetworkB. But IPs/machines from NetworkB will not be allowed to access any IPs/machines in NetworkA. What would be the best practice? Using VLANs? IPTABLES? My first thought was to assign the WRT54G two IP addresses on the BR0 interface Code: ifconfig br0:0 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255 ifconfig br0:1 192.168.2.1 netmask 255.255.255.0 broadcast 192.168.2.255 and put switch port 1 in VLAN2 and switch port 2 in VLAN3. Additional switches (for each network) would be attached to the switch ports on WRT54G. I have not tested this configuration yet but if it works it probably will not let me access NetworkB from NetworkA. Any suggestions or hints how to accomplish my configuration?
