Dropping packets??

I use the virtual interface for my virtualhosts under Apache. Apache likes
it that way and seems to work nicely with it..
To answer your questions, please let me know if all this looks correct, it
appears correct to me:
--
[root at sparky init.d]# arp -a sparky.audionautomation.com
arp: in 1 entries no match found.
[root at sparky init.d]# arp
Address HWtype HWaddress Flags Mask
Iface
netopia ether 00:00:C5:79:72:74 C
eth0
--
Netopia is the router. 63.113.184.225 and also 10.0.0.2 on the internal
network.
--
[root at sparky init.d]# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
63.113.184.224 0.0.0.0 255.255.255.224 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 63.113.184.225 0.0.0.0 UG 0 0 0 eth0
0.0.0.0 63.113.184.225 0.0.0.0 UG 1 0 0 eth0
--
As for my router:
--
Range Name: Worldcom IPs
Type... static
First Public Address: 63.113.184.225
Last Public Address: 63.113.184.254
--
Options for Type are static, dynamic or pat.
And my NAT map list:
--
First Private Address: 63.113.184.225
Last Private Address: 63.113.184.254
Use NAT Public Range... Worldcom IPs
Public Range Type is: static
Public Range Start Address is: 63.113.184.225
Public Range End Address is: 63.113.184.254
--
And my static route info from the router:
--
Static Route Enabled: Yes
Destination Network IP Address: 0.0.0.0
Destination Network Subnet Mask: 0.0.0.0
Next Gateway IP Address: 206.114.227.1
Route Priority... High
Advertise Route Via RIP: No
Static Route is a Default Gateway

My thought is that the virtual interface eth0:0 could be confusing your
router, since the problem takes some time to manifest. I believe Linux
keeps track of MAC addresses tied to IP addresses, if the router gets a
request from an IP it does not recognize it may become confused.
I forgot what type of router you were using..... you might want to see
what data you can extract from it also.
What does; arp -a YOURHOSTNAME and route -n say?
Is there really a need for the virtual interface????
