I just found this:
http://svn.dd-wrt.com/ticket/3959


This describes my Problem to 100% - is there already a fix to this? Sad

Still got this issue in the newest build:
My clients (WLAN and LAN) dont have internet access, but it works on router (for example, ping 8.8.8l8 while connected via ssh).
Still think there is an NAT Issue? How can i troubleshoot this? Sad

I've just reopened ticket http://svn.dd-wrt.com/ticket/3959#comment:5

Additionally, I'd like to draw your attention to http://svn.dd-wrt.com/ticket/4033
It seems related and maybe you have some hints there for better troubleshooting. Read it and report back, maybe it's exactly the same bug and it's not fixed yet (or just partially fixed).

I dont think this fits to my problem: When i hit "apply Settings", the clients get immedately internet access.
The Ticket only rerefers to an active PPPoE server too, right?

(Also, is there a way to run this "Apply Settings"-Command with a cron job? It would be okay for me...)


Code:
The routes look the same but there is something wrong with iptables, i think. Especially the nat rules, these WAN-IPs are missing if it is not working! (for example when i use stopservice wan and startservice wan, they are gone, ater "Apply Settings" they are listed like this:
iptables -t nat -L


root@DD-WRT:/tmp/cron.d# iptables -t nat -L
Chain PREROUTING (policy ACCEPT)
target     prot opt source               destination
DNAT       icmp --  anywhere             x-x-x-x(wanip).adsl.highway.telekom.at to:192.168.0.1
