can not ping on two virtual nic cards

Hi all,

I can not seem to find a solution to a small problem.

I am running Apache 2.054 on a AMD Sempron 2800 I have 5 static IP's.
I have setup eth0: on xxx.xxx.3.235
eth0:1 -> xxx.xxx.3.236
eth0:2 - xxx.xxx.3.237

I can get to the .235 ip number ok

--- xxx.xxx.3.235 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2001ms
rtt min/avg/max/mdev = 106.752/122.472/153.108/21.667 ms

but when I try to goto any other ip number (.236 or .237) it times out.
If i ping the ip .235 works ok, but both .236 and .237 I get sommething like

--- xxx.xxx.3.236 ping statistics ---
13 packets transmitted, 0 received, 100% packet loss, time 11997ms

If I ssh into my server I can ping all 3 ips ok

--- xxx.xxx.3.236 ping statistics ---
4 packets transmitted, 4 received, 0% packet loss, time 2999ms
rtt min/avg/max/mdev = 0.023/0.027/0.033/0.003 ms

--- xxx.xxx.3.237 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 1999ms
rtt min/avg/max/mdev = 0.029/0.032/0.034/0.002 ms

This is the results of my ifconfig

Anyone have any ideas where to look? Thanks for any help.
