Hello all,

I help a friend to upgrade his Bering-U (v2.2.2 - kernel 2.4.26) to the latest and greatest v2.4-beta1 (kernel 2.4.32) and at the same time move from PC to WRAP box. He has 2 static IPs (x.x.x.11 and x.x.x.12) and the setting in network/interfaces file on the old router is

auto eth0
iface eth0 inet static
       address x.x.x.11
       netmask 255.255.255.0
       broadcast x.x.x.255
       gateway x.x.x.1
       # secondary IP
       up ip addr add x.x.x.12/24 dev eth0

I use the same settings for the new etc.lrp on WRAP box.

From the old router, I can ping both IP, x.x.x.11 and x.x.x.12 from outside.
But when booting WRAP, I can ping only the first one, x.x.x.11 but not the other. We also turn on shorewall logging to make sure ping is allowed and we did not see anything regarding this 'ping'. My friend rebooted the ADSL modem but results are the same. When he connect back to the old router, things are OK again and I can ping both IPs.

Is that possible that the ISP keeps the old information about the card (e.g. MAC address) and so we need to turn off ADSL for a while to flush the cache or the syntax in 2.4.32 kernel has changed or is there anything I did wrong?

Thank you for any suggestions.
