New oleg firmware version

**wpte** · 21-03-2011, 10:48

I got a lot of these when using openvpn:

Code:

Mar 21 11:48:40 kernel: Call Trace:

I got r2845 installed

Please try r2837, will bug appear? If yes, try to turn off fastnat by

Code:

nvram set misc_fastnat_x=0

I can't flash firmware atm since the router will crash after firmware flash & shutdown.
Anyway, I thought fastnat was disabled by default, I turned it off and rebooted which solved the problem

All my internet is tunneling through openvpn again

Unfortunately, Broadcom's fastnat isn't as smart & flexible as can be imagined. theMIROn tries to improve it, but it is not so easy task.

Yeah, I've seen the conversation on google code.
Isn't fastnat just faster because it isn't completely compatible with some networking things?

I think the fastnat patch is good since you have more performance, unless you use something like openvpn

Also not many people have that internet speed, yet

Got some other kernel messages going on using r2849 which appeared a couple of times while downloading:

Put somewhere in /usr/local/sbin/post-boot

Code:

I think the UPnP deamon is dead again

On several computers that used to work with upnp it simply won't show up anymore.

And when I run my little tool that discovers the devices using this broadcast string:

Code:

string req = "M-SEARCH * HTTP/1.1\r\n" +
            "HOST: 239.255.255.250:1900\r\n" +
            "ST:upnp:rootdevice\r\n" +
            "MAN:\"ssdp:discover\"\r\n" +
            "MX:3\r\n\r\n";

the router simply does not respond to that packet, other devices do tho

**ryzhov_al** · 15-04-2011, 08:43

Even after restart?

Code:

$ cat /opt/usr/sbin/clearupnp.sh
#!/bin/sh
killall upnp
for line in `nvram show | grep "forward_port" | sed "s/ //"`
do
 i=`expr index $line "="`
 let i=i-1
 rule=`expr substr $line 1 $i`
 nvram unset $rule
done
upnp -D -L br0 -W ppp0

That seems to work, probably because killall says there's no upnp running.
I do have it enabled in the web-admin.

I edited your script a bit so that it knows what lan and wan is:

Code:

#!/bin/sh
killall upnp
for line in `nvram show | grep "forward_port" | sed "s/ //"`
do
 i=`expr index $line "="`
 let i=i-1
 rule=`expr substr $line 1 $i`
 nvram unset $rule
done
upnp -D -L `nvram get lan_ifname` -W `nvram get wan_ifname`
