All,
I'm relatively new to the world of hacking my router, and if it wasn't for sites like this then I wouldn't have got anywhere, so thanks for all the help.
I have been experimenting with both Kong and Voxel f/w, and have eventually decided on Kong for now, and have now noticed a very frustrating issue that I have thankfully fixed, therefore thought I would share
I am connecting to SKY FIBRE, and I appeared to be losing the connection randomly. But I noticed it was actually due to the DHCP lease expiring every hour. So after much reading on various other sites and the DD-WRT Wiki have found a solution.
I have quoted from this forum/post (so credit elsewhere), but thought I'd repeat some important points;
https://www.dd-wrt.com/phpBB2/viewtopic.php?p=774907
- It appears that by default DD-WRT firewall blocks all random incoming traffic, unless the router itself has sent out a request first
- In the case of renewing a DHCP lease, your ISP will send a renewal (to port 68), but it gets blocked because your router never requested it
- The lease will therefore expire causing the router to lose connection (and in my case causing issues on the LAN)
So the way fo fix it is to execute a script to manually open up the required ports to allow incoming traffic from your ISP;
iptables -I INPUT -p udp --sport 67 --dport 68 -j ACCEPT
I have manually run this in the DD-WRT WebGUI command shell, but plan to save it in the "Save Firewall" section so it runs automatically
So far, my router has maintained connection for a few days, so hopefullt the issue is fixed
Thank you, ver useful information!
