IP configuration and arp
Posted: Tue Aug 30, 2011 10:35 am
I have got a /224 subnet I want to route.
The adsl router can route this.
Example 205.205.129.128/255.255.255.224
I setup eth0:1 as 205.205.129.129/255.55.255.224 up to eth0:30 205.205.129.158/255.255.255.224
The router then sends arp packet out to 205.205.129.128
I am forced to set static bindmac to of all these ips o the Mac address of the eth0 card.
Support asked me ;
Can we change some setting on the web server for forcing replying ARP?
If we can find it out, we don't need to setup static ARP on router.
If I try to ping 205.205.129.128 it tells me o use -b to ping broadcast (which I do and get no reply). However I get a reply over WAN externally, so the server is not even trying o ping or it's blocking.
Any ideas?
