iproute2 + multigateway and wrong src address for gateways

Hello!

I've been searching quite long for the answer, but I found only those
docs that I've tied,
so (as the act of desperation ) I beg you for help.
So, what is the problem? That is it:

I have 2 internet links form different ISP. iproute is configured
acording to

http://www.ssi.bg/~ja/nano.txt

but there is a problem, wrong src IP is selected:

<code>
root@sdnet:~# ip r g 204.152.191.6
204.152.191.6 via 80.53.46.X dev eth3 src 193.24.245.Z
cache mtu 1500 advmss 1460 hoplimit 64
</code>

where 80.53.46.X is a GATE on interface eth3 and 193.24.245.Z is the IP
of eth2

It cause that packet goes out via eth3, but answer comes back via eth2
(depending on SRC_IP)
where the packet can't be matched with any connection, and it's droped

SB had sth like that? SB solved it?
I'll be very pleased for any kind of respod.

TIA
