<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">That does not seem as a valid command. I enabled proxy-arp and got the solution i expexted, hope without unwanted effects. <br>

<span style="font-size:11pt; font-family:Calibri,sans-serif; color:#1f497d">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>
