Dinh Tran Posted June 20, 2006 Report Share Posted June 20, 2006 Hi, I want my machine 192.168.242.1 become a arp proxy for 192.168.242.2. I entered this command: arp -Ds 192.168.242.2 eth0 Using arp -n, I verify that 192.168.242.2 is displayed on the list. When I try to ping from another machine to 192.168.242.2. I can see a arp who-has arrived to 192.168.242.1 but no reply found. Anyone of you have experience about this please help me!!!!! Thanks a lot, Best regards, Dinh Tran Quote Link to comment Share on other sites More sharing options...
paul Posted June 20, 2006 Report Share Posted June 20, 2006 does 192.168.242.2 exists? 192.168.242.2 still needs to exist on the network even though you are proxying it. and you should only see the proxied ip from some other network. example: 10.10.10.10 -> 10.10.10.1 (router) 192.168.242.1 / proxyarp 192.168.242.2 -> 192.168.242.2 so if you are on the 10.10.10.10 machine you could ping 192.168.242.2 and get a response from the proxied IP address Quote Link to comment Share on other sites More sharing options...
Dinh Tran Posted June 21, 2006 Author Report Share Posted June 21, 2006 No, it doesnt exist. But I think we dont need that, right? Quote Link to comment Share on other sites More sharing options...
paul Posted June 21, 2006 Report Share Posted June 21, 2006 proxyarp forwards the request to the real interface, so the IP needs to exist first. if you want to have move than one IP on a machine then you need to use interface aliases not proxyarp Quote Link to comment Share on other sites More sharing options...
