I tried the following rules and had the same bad latency results for
the corp site to remote site. Below are the rules I tried which gave
the bad (avg. 350ms) latency:
----corp rules----
tc qdisc add dev ipsec0 handle 1: root cbq bandwidth 600kbit avpkt 1000
tc class add dev ipsec0 parent 1: classid 1:1 cbq bandwidth 240kbit
avpkt 500 prio 1 rate 240kbit bounded isolated
tc filter add dev ipsec0 parent 1:0 protocol ip prio 100 route
tc filter add dev ipsec0 parent 1:0 protocol ip prio 1 u32 match ip dst
10.0.1.20 flowid 1:1
tc filter add dev ipsec0 parent 1:0 protocol ip prio 1 u32 match ip dst
10.0.1.21 flowid 1:1
tc filter add dev ipsec0 parent 1:0 protocol ip prio 1 u32 match ip dst
10.0.1.22 flowid 1:1
----remote rules------
tc qdisc add dev ipsec0 handle 1: root cbq bandwidth 580kbit avpkt 1000
tc class add dev ipsec0 parent 1: classid 1:1 cbq bandwidth 240kbit
avpkt 500 prio 1 rate 240kbit bounded isolated
tc filter add dev ipsec0 parent 1:0 protocol ip prio 100 route
tc filter add dev ipsec0 parent 1:0 protocol ip prio 1 u32 match ip dst
10.0.0.7 flowid 1:1
Any help would be greatly appreciated.

Subject: [LARTC] 2 internal nets, each one with its own provider
Hi, and good evening,
I encountered a quite weird problem yersterday evening, and I wonder
if someone can explain the way of it. Anyway, there is goes :
I have a client running two separate networks, NET-A (10.0.1.0/24) and
NET-B (10.0.2.0/24) and two providers P-A, with gateway 192.168.0.1 and
P-B with gateway 192.168.0.2. Now, as for the hardware part of it, there
is one linux router hosting 4 ethernet cards on it, each connection
having its on ethernet device, something like this :
+-------------+ P-A
eth0 |
+------+-------+
eth2 | if1 |
NET-A -------+ |
| Linux router |
eth3 | |
NET-B -------+ if2 |
| |
+------+-------+
eth1 |
+-------------+ P-B
Hope you get the idea. As for the configuration, what I did was :
setup 2 new routing tables, for P-A, and P-B, added the default gws to
those tables, and setup 2 snat rules for the two networks in order to
get each of them out on a separate provider. That does not seem to work,
and I wonder if anyone has any idea why.
Excuse me for the large email, and thankyou for your patience :)
Cezar
