no. he can subnet it
Typically ISP can assign /20. but client can subnet it
two networks /22 /22
or
16 networks /24
Thank you

no, no, NO. his eth1 connection is from his ISP. He /has/ to use
the supplied netmask, he can't reconfigure their network segment.
now, why is ARP table is overflowing is another issue entirely.
Thomas, can you try this? Do....
arp -an | grep 65.188.0.1
and pick out the "MAC" address of your gateway router, this will look
something like...
? (65.188.0.1) at 00:17:CB:4F:97:81 [ether] on eth1
So, the MAC address above is 00:17:CB:4F:97:81 ... yours definitely will
be different.... now,
# tcpdump -i eth1 -n ip host 65.188.xxx.xxx and not ether host
00:17:CB:4F:97:81
(replacing that with your gateway router's MAC address as determined
from that ARP command, and xxx.xxx with your eth1 IP address as shown in
`ifconfig eth1`)
this will catch all traffic between you and another IP on your ISP local
segment thats NOT talking to the gateway router
paste 50 lines or so of the output of this here and maybe we can figure
out whats going on.
