I know why and I can't explain it. 
The router sees the IPX number 2222.2222.2222 and 5555.5555.5555 as well as all other matching numbers as a multicast address I dont know why but try to define a static sap and it wont let you. It says that its a multicast address.
Use the address 2.2.2 or 5.5.5 as your IPX internal address and it will work.

Hi,

has anyone seen the following  IPX problem where you can ping from one
spoke to another spoke but not vice-versa?
It looks like R5 is treating the ipx ping from each spoke differently. Why?
I think it is the OS versions - but very wierd.



                         S0                   ipx network 200 on E0
      /---------------------------R2 ipx routing 2222.2222.2222
    /
R5 ipx routing 5555.5555.5555
   \
     \-------------------------------R3 ipx routing 3333.3333.3333
                        S0                      ipx network 333 on Token 0


R5 is the frame hub.
R5 has no ipx split-horizon eigrp 1
R5 uses subinterfaces
R2 and R3 can see each others routes via EIGRP.

Frame is ipx network 5130

R2 can ping R3 on Frame network 5130
R2 can ping R3's token interface 333
R5 can ping R2 and R3 on Frame
R5 can ping R2 E0 and R3 token interfaces

R3 CANNOT ping R2 frame or Ethernet 0 interface.

A debug ipx packet on R5 shows the following when pinging from R3 to R2:

Now look at a debug when I ping from R2 to R3 - notice how it looks like R5
is directly answering the pings:
