Hello everyone,
i’ve got 3 pppoe connections, 3 wan ip address;
then created 3 snat rules for these ip:
nat one transmission lan server to port 9011 @ In-Interface “all-ppp”;
route table as this:
PCC done, NO flow-back nat rules added.

PROBLEM:
I can only access internal transmission server from ip of pppoe-out2. if i access internal server from pppoe-out1, I’ll got this :

see the marked line. the final packet is come out from pppoe-out2 with source ip of pppoe-out1.
if i access from pppoe-out3, final packet comes out from pppoe-out2 and caused error also.
I think ISP blocked ip packets from error source then lead to this result.
QUESTION:
Why the s-nat rule doesn’t work at this packet? How can I access internal server from all 3 dynamic wan ip?
