[7.250] Gateway Policy Route stop to work [NOTABUG]

My Gateway Policy route for ftp stops to works without a reason.
My configuration:
2Mbit SDSL (Def GW)
16MBit ADSL (no daily disconnect, static ip)

i route ftp traffic to the ADSL Line, after a night FTP stop to work,
disabling/enabling Police Route resolves this problem.
(Policyroute for HTTP still work)

Not sure where i have to look if this error occurs....

I guess this is related to the daily (nightly?) SDSL reconnect. Can you confirm by triggering a reconnect manually (power-cycle SDSL router) please?

Thanks!

Both of my lines dont have a daily disconnect/reconnect.

After manualy disconnect/reconnect ADSL all policy routes stop to work.
After reboot (eg install 7.260) all my policy routes stop to work.
I have to disable and renable all to got it working again.

OK, so this affects all policy routes, not only the one which does FTP?

A reboot affects all Policy routes.
After night only ftp route stop to work.
Maybe the firewall make some cleanups/restarts of services after 24:00 ?

Can you verify there is no reconnect entry in /etc/crontab ?

You can verify the policy rules with these commands:

# ip rule
0: from all lookup local
1: from all fwmark 0x1 lookup 1
32766: from all lookup main
32767: from all lookup default

# ip show table 1
default dev eth0  scope link

# iptables -L -v -n -t mangle

Sorry, typo in command.
Right one is "ip route show table 1"

As you can see in POLICY_ROUTING_PRE, there a three policy routes
  117  4680 MARK       all  --  eth3   *       192.168.177.0/24     0.0.0.0/0           MARK match 0x0 MARK set 0x1
    0     0 MARK       tcp  --  *      *       213.148.150.210      0.0.0.0/0           tcp spts:1:65535 dpt:80 MARK match 0x0 MARK set 0x1
    0     0 MARK       tcp  --  *      *       213.148.150.210      0.0.0.0/0           tcp spts:1:65535 dpt:443 MARK match 0x0 MARK set 0x1

One for network 192.168.177.0/24, one for HTTP and one for HTTPS.

So the FTP rule is missing ?

The policy route for FTP is disabled because it stops to work, i am to lazy to disable/enable it every morning, i will recheck it on monday. [:)]

But after reconnect dsl the 3 routes in POLICY_ROUTING_PRE also dont work.
