Hi,

in my two ISPs Setup every package except that for aaa.117.77.217 should be 
routed via the ppp0 (tcom) interface.

provider:
tcom    1       0x100   -               ppp0            -               
balance=2       -
netco   2       0x200   -               eth4            aaa.117.77.217  
balance=1       -

tcrules:
#alles über tcom:
0x100:P 0.0.0.0/0
0x100   $FW
#Meb via netco
0x200   -              aaa.117.77.202

shorewall show ip:
3: eth4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 
1000
    inet aaa.117.77.218/29 brd aaa.117.77.223 scope global eth4
    inet aaa.117.77.222/29 brd aaa.117.77.223 scope global secondary eth4:0
    inet aaa.117.77.219/29 brd aaa.117.77.223 scope global secondary eth4:1
92: ppp0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1492 qdisc pfifo_fast 
state UNKNOWN qlen 3
    inet bbb.152.162.192 peer 217.0.117.221/32 scope global ppp0


As far as I can see the routing via ppp0 is ok, but not so is the source IP. 
It's switching between the ppp0 and the eth4 IP. And obviously there are no 
answer packages for the aaa.117.77.218 sourced ones.


tshark -i ppp0:
0.473136 bbb.152.162.192 -> 141.76.2.4   TCP 68 43768 > http [ACK] Seq=2848 
Ack=2262 Win=27392 Len=0 TSval=279996039 TSecr=2412064345
1.001138 aaa.117.77.218 -> 195.20.242.89 TCP 76 35771 > http [SYN] Seq=0 
Win=14600 Len=0 MSS=1460 SACK_PERM=1 TSval=279996171 TSecr=0 WS=64


What's wrong with the shorewall config?
