Hi,

I have the issue with incorrect SNAT.

I have two interfaces, let's say ppp0 - x.x.x.x, ppp1 - y.y.y.y ppp0 is 
a default gateway.
I use some command to change routing to IP z.z.z.z via ppp1:
ip ro ad to z.z.z.z dev ppp1

I have SNAT rules for both interfaces, however, I notice with tcpdump 
that outgoing packets are still using x.x.x.x instead of y.y.y.y IP, 
though packets are being sent with the correct interface (ppp1)

I have shut down ppp0 and removed SNAT rule for it, but outgoing packets 
are still showing x.x.x.x IP. Even, ip ro fl cache didn't help.

Is there anything I am doing wrongly? I suppose this is some unwanted 
behaviour.
