Edgepoint ER8 proxy arp on bridged interfaces issue

Hello,

 

I am replacing Mikrotik routers with Edgepoint and while transferring configurations I noticed that proxy arp is not working the same way as on Mikrotik devices. I need proxy arp for "public ip routing". If I enable proxy arp on a specific ethernet device then everything works as expected. But if those ethernet ports are bridged then I am not getting it thorugh. Is it supposed to work like this or I am missing something?

 

More details:

EdgePoint Router 8-Port v1.9.1

 

 bridge br0 {
     address 172.16.44.250/24
     address 172.16.45.250/24

Re: Edgepoint ER8 proxy arp on bridged interfaces issue

proxy-arp is a layer 3 thing.

If you need it enabled on the bridge ports,  enable it on the L3 br0 port.   Not on the L2 eth ports belonging to the bridge.

That was my first thought. But when I first checked throughout the options for bridge I did not found anything related to proxy arp on bridge. So I am still stuck. Do you know where should I enable it on bridge?
