network doesn't transmit MAC addresses

Hi,

My main AP is Mikrotik 411AH ROS 3.22

I've problem. When I use command arp -a I see just client AP MAC

10.0.0.26 mac1 dynamic
10.0.0.45 mac2 dynamic
10.0.0.47 mac2 dynamic

mac1 belongs to AP-client Ovislink (192.168.1.247) not to 10.0.0.26, similar to mac2 (it's Straightcore) (192.168.1.250)

is this normal behavior? Should I try to set IP of APs (192.168.1.x) to same network as clients (10.0.0.x)?

thanks

When I use command arp -a

I see MAC adresses on local wired network right but wireless connection makes troubles.

wlan1: 10.0.0.249 [mac of ether1] dynamic
ether1: 10.0.0.254 [mac of ether1] dynamic

isn't this problem?

I have new R433AH with ROS 3.25 and there is the same problem (connected to ether1, when connected to other etherX - I see this mac instead ehter1's mac)

wlan1: 10.0.0.149 [mac of ether1] dynamic
wlan2: 10.0.0.150 [mac of ether1] dynamic
ether1: 10.0.0.152 [mac of ether1] dynamic
ether2: 10.0.0.153 [mac of ether1] dynamic
ether3: 10.0.0.154 [mac of ether1] dynamic

I've bridged all interfaces together.

Other situation:
me(10.0.0.3)--->R433AH(10.0.0.254-ether1,10.0.0.249-wlan1)~~~>Ovislink(192.168.1.247)--->PC(10.0.0.26)
I see MAC adress of Ovislink on PC IP
10.0.0.26 [mac of Ovislink] dynamic

I don't know why I can see some mac right - like gateway and FTP server (but now I can list of FTP folders but I can't download from behind of wireless bridge)
me(10.0.0.3),FTPserver(10.0.0.2)--->R433AH(10.0.0.254-ether1,10.0.0.249-wlan1)~~~>Ovislink(192.168.1.247)--->PC(10.0.0.26)
me can download from FTPserver but PC can't.

I've tried to change IP of Ovislink to 10.0.0.247 but no change - still no downloadability from PC ... Isn't the problem with this type of addresses? Should I try 192.168.1.x? Or should help 10.0.1.x? mask is 255.255.255.0.

It sounds like you're masquerading traffic that doesn't need to be NAT'd at all.

I don't know where the problem is ... I could give you information from my settings, but I don't know what information you need, so please ask freely :D

I switched all ARP settings on my RB to enabled, IMHO no masquerade is set.

check interface ARP, maybe it is set to reply only. also, you seem to see one network through both interfaces, this is intended to be so?

edit:

could be nice if you could draw some network diagram to better unsterstand why and what shows up.

I've solved downloading from my FTP server. There was arp=proxy-arp setting in bridge so I changed it to enabled and it runs now...

What I didn't know - that I can't see MAC addresses after client APs ... never mind. :D
