Sergio, I think your network diagram is wrong. By its very nature the modem has to connect to the Internet directly so I think the router is actually is actually on the network side of the "DSL Ericsson's modem".
That aside, just turn off DHCP on the modem/router and assign it a fixed IP address if you can and use the ouput from the modem/router box as your input to the Linksys box and set the Linksys external (WAN) IP address to whatever the IP coming out of the modem/router. N.B. Make sure the range of IP addresses used bu the DHCP server conflict with any static address you define.

(suggestions on where to ask this are accepted) I'm using a DSL modem router Ericsson connecting using pppoe that have a nat and DHCP providing one LAN address (10.0.0.4) to a WIFI Linksys Router that get that LAN address as its WAN address and provide nat and DHCP to the "real" lan 192.168.1.xxx wired and wireless machines. Graphically: {Clients} ----->WIFI Linksys Router-------> DSL Ericsson Modem Router ------> Internet (192.168.1.xxx) (192.168.1.1/10.0.0.4) (10.0.0.1/dyn public ip address) I'm not a IP/Network expert but I'm sure I'm doing something wrong using 2 routers(with its services nat,dhcp,etc.) to provide internet access to the lan computers. My question is which is the 'elegant' way to provide internet access to the lan with this equipment? should I convert the WIFI Linksys router into an access point? is this possible?, how? The DSL Ericsson modem router has a bridge feature, but not sure how to use it. Any ideas are welcome!! Thanks in advance!

The Mac is already a true NAT router in and of itself, not a bridge. Its second NIC connects to a hub, and the rest of the LAN uses that interface's IP, 192.168.2.1, as the gateway. > > > > "Elegant" would be eliminating one or the other router and its address translation. John's is the elegant solution--change the netmask simultaneously with the Size of Client IP pool, and attach the ZyXEL to the hub. This relieves the Mac of its need for a second NIC, reducing rather than increasing the hardware involved. > > > > Thanks to everyone for sharing your knowledge. The only unanswered question is how one would talk to the device at all if it became a bridge. That one's for ZyXEL. > > --__--__-- _______________________________________________ VNC-List mailing list [email protected] To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list _______________________________________________ VNC-List mailing list [email protected] To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
