[LARTC] About two IFs with the same IP and the multipath

[Alpt]

Hi there,

I'm trying to achieve the classic load balancing using the multipath.

The gateways are:
	A (tunl0)  and   B (tunl1)

This is the classical situation covered by the HOWTO: one computer with two
Internet connections.

The problems come when I try to use the same IPs for both A and B.
So A is 10.229.25.8 and B 10.229.25.8.
I cannot do otherwise, I'm forced to use the same IPs.

For the rules which select the sources I've tried to use the `iif' option
instead of the `from' one.

32764:  from all iif tunl1 lookup main 202
32765:  from all iif tunl0 lookup main 201

These rules don't work and this means that the packets choose a different gw
each time and the TCP connections are killed.

I've tried also with:

32764:  from 10.229.25.0/24 iif tunl1 lookup 202 
32765:  from 10.229.25.0/24 iif tunl0 lookup 201 

and 

32764:  from 10.229.25.8 iif tunl1 lookup 202 
32765:  from 10.229.25.8 iif tunl0 lookup 201 

but with no results.

Is there a way to solve this problem? A netfilter hack?
