Just do the factory reset option under the admin tab, then don't mess with any of the remote admin settings. By default DDWRT is locked down to not allow remote admin, you have to change the settings to enable remote admin. But it IS allowing remote admin.

Why can't my firewall deduce which client a response is sent to?
When a response outside packet later arrives at the NAT device (firewall), it can not deduce which client to send it to. Here are examples of protocols that has that problem:
How many devices can I use with Wemo remote access?
Remote access for WEMO is one handheld device per WEMO network and account. Please use only one smart device per WEMO network to prevent remote access errors and conflicts. The F7C027UK & F7C029UK are designed for UK region.
Why does a firewall need to be Nat aware?
Due to IPv4 address shortage, the internet society began to use NAT, and therefore the firewall also need to be NAT aware. A real problem with NAT is when more than one inside clients (e.g. C1, C2) connect to the same outside server ip address (S) and the traffic is not tcp and udp.
How do I access my DD-WRT remotely?
Go to Administration -> Management -> Remote Access. Enable the necessary settings for remote Web or SSH access (note the WAN IP and port number), then in your main router forward that port to the WAN IP address of the Repeater.
Does DD-WRT have firewall?
DD-WRT has a packet filtering firewall, statefull firewall, NAT and proxy functionality. The default internal device network has two networks (non-802.11n example!): vlan0(built-in hardware switch) software-bridged with eth1(wireless access point) - LAN private ip subnet 192.168.
What is the default IP address for DD-WRT?
192.168.1.1After installing DD-WRT Firmware you can access the DD-WRT Web-GUI using a web browser pointing to the same IP address as before you installed DD-WRT. These are some of the most common default IP addresses: 192.168. 1.1 (most commonly used on Linksys and Asus), 192.168. 2.1 (some Belkins), 192.168.
How do I block an IP address in DD-WRT?

Change your router's network settingsSelect set number: Select 1 ( ).Route Name: Enter a name that will help you recognize this route.Metric: Enter 2.Masquerade Route (NAT): Check this box.Destination LAN NET: Enter the IP address you wish to block.Subnet Mask: Enter 255.255.More items...•
What is Filter WAN NAT redirection?
Filter WAN NAT Redirection Prevents hosts on LAN from using WAN address of router to contact servers on the LAN (which have been configured using port redirection).
Why DD-WRT is better?
Essentially, it echoes the signal to widen its range. With DD-WRT, you can take a regular router and make it into a range extender. A stronger, better, optimized DD-WRT signal may also be able to more easily reach farther devices, even without a range extender.
How do I access DD-WRT Repeater Bridge?
Go to the wireless tab.Choose Repeater Bridge under wireless mode.Match your SSID and channel settings exactly to the main router you will be connecting to.Make sure bridged is selected.Click Save.
How do I find my DD-WRT password?
Both routers have a password of "admin" by default. Click on "support and documentation" in your router's manufacturer's website to find out their default password.
Does DD WRT have parental controls?
In general, every device on network is restricted except the well-known parental devices. It means that every household guest is restricted by default, e.g. when a child's friend comes to visit, they are restricted as well. Remember that this tutorial protects your children at your home only.
What is the purpose of a firewall?
The purpose of the firewallis to moderate traffic and/or log it . Most firewall are made for moderating ip traffic and are called ip firewalls. The simplest ip firewall has two physical interfaces normally referred to as inside(LAN) and outside(WAN, the internet).
Why do firewalls need NAT?
Due to IPv4 address shortage, the internet society began to use NAT, and therefore the firewall also need to be NAT aware.
What is the simplest IP firewall?
The simplest ip firewall - a packet filter firewall - can pass packet by packet or drop them based on:
What happens if you enable proxy support for active FTP?
FTP active - if you enable proxy support for active FTP, you firewall can be "punctured" from the internet and is therefore almost useless.
Can you NAT a response outside packet if the traffic is unencrypted?
Even if the traffic is unencrypted it can not be deduced where to NAT a response outside packet, if more than one inside client uses the same protocol to the same outside ip address. UDP and TCP are special because they have 65536 possible src and dst ports that can help connection tracking.

Hi, i just noticed that I can access/login my router's web admin interface by visiting my external IP address from outside my network. i thought i shouldn't be able to do this?
primexx
doesn't work either, that governs remote access (web gui managemnt, ssh, telnet).

Disabling Remote HTTP access shouldn't stop internal IP addres's. It should only stop access from the WAN port.

Are you sure your accessing it externally? Like your not on a VPN or not still connected to the wireless or something of those lines. I know its a stupid question but I have made some silly mistakes before too.

yea i've been trying from a web proxy and also my neighbour's open wifi, can access it in both. i don't have vpn.

ok turns out the firewall rules were all messed up somehow. it's good now.
Packet Filter Firewall
- The simplest ip firewall - a packet filter firewall - can pass packet by packet or drop them based on: 1. source ip address 2. destination ip address 3. If tcp or udp: 3.1. source tcp/udp port 3.2. destination tcp/udp port
Statefull Firewall
- The better ip firewall - a statefull firewall - can pass packet by packet - and if possible (e.g. tcp and udp) track the connection. A statefull firewall can additionally moderate trackable traffic by: 1. number of connections per (src/dst) ip address 2. number of connections per interface 3. number of connections attempt - "SYN"-attacks, packet storms
Nat - Network Address Translation
- Due to IPv4 address shortage, the internet society began to use NAT, and therefore the firewall also need to be NAT aware.
Firewall Difficult Protocols
- Some protocols can in-line signal a port jump and/or create connections one or both ways "at will". A firewall that can moderate that kind of traffic, need to inspect the traffic stream. To do that a firewall must have transparent proxies and are then called an application firewall. Some examples of protocols that can port jump and/or create additional connections are: 1. FTP passive 2. FTP …
