We have Nextiva voip at our business and Nextiva engineers are needing to troubleshoot their service with our router. They are needing to ping our router from one their ip address.
Is this done through dd wrt administration->command shell and with ip tables?
Also, is SIP ALG already disabled in the dd-wrt firmware?

On security firewall you may be able to uncheck the "Block Anonymous WAN Requests (ping)" and save an apply,
Otherwise the iptables command is:
Code:
iptables -I INPUT 1 -p icmp -j ACCEPT
This will accept all pings... it will ensure that whatever your ISP uses to troubleshoot will work.
Edit:
I forgot to add that last I knew there was no SIP ALG in DD-WRT, but it could have changed.
Hello Wildlion,
Thanks for the response! I was wondering through that ip table code, is there a way to allow one ip address to ping our router public wan ip instead of accepting all pings?
If you're interested in some cloud monitoring, you can also expand your configuration. Uptime Robot example is at the bottom of this thread.
