Hi all,
I am having a problem with my DSL line in bridged mode. It all works fine, but after a while my C837 dies on me.
When I checked the arp table, I discovered it's huge! It never stops growing and then the router hangs.
Is there something wrong with my config:
interface Ethernet0

ip address 192.168.32.1 255.255.255.0

My arp output:

Etc.
I put "arp timeout 20" in the BVI interface but this does not seem to help that much.
IOS level is: c837-k9o3y6-mz.123-2.XC2.bin
Any suggestions are welcome how I can prevent the huge number of MAC entries.
Thanks,
Rene
