I have a multipath system with 2 physicals, a virtual and a failsafe. All network connectivity is working fine to and from all of the interfaces and the virtual. The one thing that is not working is 'ping -s'. From this machine, I cannot send and receive packets using ping -s. ping without the option works fine.
While the ping -s is running, I can snoop run snoop and see that the packets are leaving one interface and returning on another. Is there anyway to fix this so that ping -s works? See code below, atiems is the IP of the virtual interface:
anyone ever seen this problem:

epair
EPAIR(4) BSD Kernel Interfaces Manual EPAIR(4)NAME
epair -- A pair of virtual back-to-back connected Ethernet interfaces.
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device epair
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
if_epair_load="YES"
DESCRIPTION
The epair is a pair of Ethernet-like software interfaces, which are connected back-to-back with a virtual cross-over cable.
Each epair interface pair is created at runtime using interface cloning. This is most easily done with the ifconfig(8) create command or
using the cloned_interfaces variable in rc.conf(5). While for cloning you only give either epair or epair<n> the epair pair will be named
like epair<n>[ab]. This means the names of the first epair interfaces will be epair0a and epair0b.
Like any other Ethernet interface, an epair needs to have a network address. Each epair will be assigned a locally administered address by
default, that is only guaranteed to be unique within one network stack. To change the default addresses one may use the SIOCSIFADDR ioctl(2)
or ifconfig(8) utility.
The basic intend is to provide connectivity between two virtual network stack instances. When connected to a if_bridge(4) one end of the
interface pair can also be part of another (virtual) LAN. As with any other Ethernet interface one can configure vlan(4) support on top of
it.

The epair interface first appeared in FreeBSD 8.0.
