Im quite new in ClearOS and Linux in terms of DHCP/Routing
Before any further explanation, below simple diagram
[INTERNET] --- [MODEM] --- (NIC1) [CLEAROS SERVER] (NIC2) ---> [LAN]
External IP (from modem) : DHCP - no problem
LAN IP : 10.10.10.1/23 (255.255.254.0)
DHCP LAN : 10.10.10.2 - 10.10.11.254
IP Forwarding enabled, net.ipv4 = 1 (idk, just google around but seem it already "1" in /proc/net/ipv4/forward)
<blockquote>The Situation</blockquote>
I want to expand my LAN network to host 512 +/- IP address.
<blockquote>The Problem</blockquote>
- DHCP range from 10.10.10.1 - 10.10.10.254 is getting internet <blockquote>BUT</blockquote> 10.10.11.1 - 10.10.11.254 get DHCP too but NO INTERNET (No error shows i mean like WiFi no yellow windows sign)
im afraid i don't know how to do routing or did i miss something? Please help me
guide me. Thanks and sorry if the topic already posted by someone else, ive tried search but no dice.

As a hint in putty, if you select text, it is automatically copied to the clipboard and a right-click will paste into the screen, so you can copy text straight out of putty and paste it between code tags on the forum.
The transparent proxy rule at the end of the prerouting chain is correct and does not depend on the subnet.
You can see the routing table with "ip ro".
Have you tried disabling the proxy? -

The networking looks good so I suspect the proxy which I don't know. You can check the firewall with a "iptables -nvL -t nat". Paste the results from putty between code tags (piece of paper icon with a <>
. I can't give any more help with the proxy as I am away and can't play with my system. You could try temporarily disabling it to see if it is the problem. -
