<span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);">I have a setup where several vlan’s are connected to the same multibind interface and are assigned ip addresses from the same subnet. The problem I face is that communication
btw customers from different vlan’s is impossible(they think they are on a L2 domain and ARP will do the trick but ofc that does not happen) . I think enabling proxy-arp would help me in this case but I am just wondering if there is something I should be careful
regarding enabling that – being a live setup interruptions are not welcome..</span></p>
