I understand the idea of proxy arp, that it allows me to communicate with other computers from other subnet, because proxy broadcast is made and router act as a proxy, but what if I disable proxy arp ? For example, I have empty arp table and I want to ping computer B. Then arp broadcast is made , but router doesn't redirect it so I won't be able to communicate with computer from others subnet ?
I know that it might be very basic question, but after reading about it I am still not able to understand it clearly. I read that having arp proxy enabled can hide subnet misconfiguration. Could someone give me an example ?
