Dual WAN working but annoying logs



  • Hi,

    My setup is two cable modems with dynamic ip addresses but they are static enough and they are not on the same subnet. Below is my configuration:

    WAN interface (vr0)
    Status up
    DHCP up 
    MAC address 00:40:63:xx:xx:xx
    IP address 24.6.189.xxx 
    Subnet mask 255.255.248.0
    Gateway 24.6.184.1
    ISP DNS servers 4.2.2.2
    4.2.2.3
    Media 100baseTX <full-duplex>In/out packets 314576/156678 (359.02 MB/10.46 MB)
    In/out errors 0/0
    Collisions 0
    Interrupts/Second 457102 total
    220 rate

    OPT1 interface (vr1)
    Status up
    DHCP up 
    MAC address 00:40:63:xx:xx:xx
    IP address 24.6.169.xxx
    Subnet mask 255.255.248.0
    Gateway 24.6.168.1
    Media 100baseTX <full-duplex>In/out packets 357628/185174 (418.44 MB/12.14 MB)
    In/out errors 0/0
    Collisions 0
    Interrupts/Second 527314 total
    254 rate

    Above are my two wans. I can see dual wan working by looking at the traffic graphs and other things like that. Now, my problem is I get the following messages in my system log:

    Oct 26 22:59:49 kernel: arp: 24.6.184.1 is on vr0 but got reply from 00:01:5c:22:64:c2 on vr1

    Oct 26 22:59:49 last message repeated 2 times

    Does anyone know what can I do to get rid of it?</full-duplex></full-duplex>



  • Do you plug both WANs into the same switch?



  • Both wans go directly from modem to port on my machine.



  • Advanced page, "This will suppress ARP messages when interfaces share the same physical network"



  • Love you guys! Never noticed that option was there until you read it out! HAHA.
