How you've adjusted your firewall settings for ssh WAN access?

[yanism]

I've the same rule as here (http://wl500g.info/showthread.php?t=385) for ssh WAN access.

this is my bootCmd :
echo 2048> /proc/sys/net/ipv4/ip_conntrack_max
/init/rc.sshd
echo "iptables -A INPUT -p tcp --syn --dport 22 -j ACCEPT" >> /var/tmp/pppoe_rule2
/var/tmp/pppoe_rule2

I've the v1.7.5.6 CR5 firmware

[Oleg]

This will only work for pppoe/ppptp/static connection. And will not work with dhcp. The prefered way is upgrading to 1.7.5.9-2 & writing post-firewall script.
In short, if you can't access ssh from WAN side, but it does work from the LAN at the same time, then it's mostly firewall problem. You can check it state using iptables -L -v

[yanism]

Yes ssh work from Lan side when it crash on Wan side. But it's strange because if it was un firewall problem, ssh doesn't work on Wan side all the time
I will upgrade to 1.7.5.9-2 to see if the problem persist.

I upgrade to 1.7.5.9-2 but the problem is the same. With this firmware i can also use ssh all the time in the lan but not by the wan. So I must rebbot the router. I've nothing in the status log which can expalin me what is the problem. It's weird.

are you still using bootCmdX ?
or do you use as suggested by Oleg the post-firewall etc?
if not than THAT is the problem!
