How can i set my OpenWrt 10.03 router to not to use 192.168.1.0/24? instead, use a /32 mask, so every client, that gets an ip from the DHCP server just can't sniff the network traffic - it would be a great security feature to safely use e.g.: FTP!
View 2 RepliesI've got threeLinux Boxes (running Centos 6). They were all connected to my cheap WRT54GL-- DHCP worked every time.Absolutely no problems. Both the LInux boxes and the WRT54GL had MTU set to manual, 1492.I replaced the WRTt54GL with the expensive E4200. I set the new router's MTU to manual, 1492. NONE of my Linux boxes ever receive a DHCP address. I look at the logs, and they do DHCPDISCOVER, get DHCPNACK, try several different intervals, and then fail the interface and quit.ALL I did was unhook cables from the WRT54GL and plug into the E4200. Yes, the WRT54GL was powered off. NOTHING was changed in the Linux configs. Yes, DHCP is enabled, address-range assigned, etc. BTW-- one box is dual boot with Win7-- in Win7 (using the same card, obviously), DHCP works just fine. But, Linux doesn't work.
I can give the boxes static IP's, and all is well. Just can't get DHCP to work. I evfen tried putting in DHCP reservations (via MAC assignments) for the E4200-- still doesn't work. The new E4200 is on the 02 firmware (which I believe is cuurent). If I can't iron this simple task out, in a couple of days I'm taking the E4200 back, and getting a refund. I'll stay with my old WRT54GL... it works. Hate to give up on some of the new E4200 features, though.
I've been playing with the OpenWRT Attitude Adjustment trunk on my TL-MR3020 lately, and since I'm modifying some of the included packages that get installed via feeds, I need to reflash the firmware a lot. And the problem here is that it's very time consuming. I'd like to optimize this process as much as possible, and the first optimization I can come up with is precluding any need for network reconfiguration after reflashing.
Currently, after I use mtd to reflash my firmware, I have to log in via the serial console and modify /etc/config/network to put the router on the right subnet, and to specify the gateway and dns. It sure would make a lot of sense if I could have this happen automatically every time.
I'm very new to Linux, so my first thought was to have a shell script run that edits /etc/config/wireless/ and then does a /etc/init.d/network restart to bring up the network interface(s). Then I thought that there must be a command-line equivalent to setting the gateway and dns, and then I could follow those commands up with /etc/init.d/network restart.
Why is it that the dhcp on my router is no longer able to give out ips or rather it assign them as for as it concerned as it will list say 199.170.0.102 but the device will have none or make up one for it's self and never get the ip that the routers dhcp gave it this happens on all devices. I know power cycling will fix it temporally but usually it will start doing it again in a few hours also I know that I can use a static ip this was my way around this problem but I have one device that won't use nothing but dhcp a printer. I had an old linksys router that did this and I figured it's old it's slow time for a new one after a few months it started, some computers are on the fringe of being able to get a signal but are still fair also even with static ips they sometime stop connecting and we have to disable the connection then reconnect to fix it the router is a dlink 615 dual band set to only G/B because 1 most devices only g 2 the one computer that has a wireless n is 70 ft away and works better with g.

View 2 Replies View RelatedI have a Cisco/Linksys E2500 router. I connected to it through one of the Ethernet ports with a Microsoft Windows XP Pro machine and installed and ran the setup software. Windows was able to connect to the router and to the internet through the Siemens Gigaset 4300 DSL modem to my internet provider, Windstream.I cannot get my Dell GX620 which is running Linux Debian 6 (Squeeze) to connect to the router through the Ethernet ports.It appears that I receive no reply to the DHCP requests made by Linux.
I have only one monitor, keyboard and mouse and no KVM switch to run both the machines at once. I do have Windows XP Pro running in a VirtualBox virtual machine on the Debian machine,I can configure Debian to a static IP if I knew all of the IP configuration that the E2500 would assign. I would also need to know what reconfiguration the router requires if I use a static IP.

View 1 Replies View RelatedI'm trying to set up a VPN tunnel between a Linux machine and a RVS4000 at a remote site (served via satellite connection). After many efforts, I finally succeeded (based on Openswan). However, while PINGing is OK, big packets (from the RVS4000 LAN to the Linux box) arrive corrupted.
I lowered the WAN MTU, with no success. What finally did the trick is to lower the MTU at the RVS4000 LAN interface. Since this is not possible via the Web I/F, I did it via telnet ("ifconfig eth0 mtu 1400"). However, this change is lost after router reboot. How can I make the LAN MTU setting permanent?
Region : UnitedStates
Model : TL-WDR4300
Hardware Version : V1
Firmware Version : OpenWRT
ISP : Comcast
I was having major stability issues with my TPLink WDR4300 and after a little bit of research, decided to upgrade the firmware to OpenWRT. I found a post online and followed these instructions:
1- Make sure your router is version 1.x (x can be any number).
2- Download the openwrt firmware from here: [URL]
3- Download putty command tool from here: [URL]
4- Login to your router config page (192.168.0.1) using internet explorer browser and update the firmware to openwrt. Use the firmware file you downloaded in step 2.
5- Now open Putty software you downloaded in step 3. Enter host name: 192.168.1.1, Connection Type choose: Telnet. Now click open. Now you will see the command line with black screen,
6- Now type "passwd" into the command line and press enter on the keyboard. Now choose your new password to access the router make sure password has letter and number. Repeat type password and press enter. Password should be changed now.
7- Type into the command "opkg update" and press enter on keyboard, Wait for it to do some download and updates. Once finished, type this "opkg install luci" and press enter
8- Type this into the command to enable luci "/etc/init.d/uhttpd enable" and press enter on keyboard.
9- Type this into the command "/etc/init.d/uhttpd start" and press enter on the keyboard. Now you can close Putty.
10- Open internet explorer in the address bar punch in: 192.168.1.1 and use the password you created to login to the router config page. Go to the wifi section and turn on the wifi and set up wireless security network.
Everything worked fine until I got to the last step and go to the "wifi section and turn on wifi." After a bit more digging, I noticed that there is not a "Wifi" option under the 19192.168.1.1 portal "Network" tab. After getting frustrated and more hours trying to figure it out, I elected to try and go back to stock firmware. On Luci, I selected restore to factory settings and the router did its thing and restarted. Now I can't login to Luci (obviously) since it was no longer enabled in Putty. I try and run Putty to connect to 192.168.1.1 and it just opens and immediately closes. It will not connect. I also can no longer login to (192.168.0.1). Further, when I try and run the TPLink setup disk,I receive the error "Please check the network connectivity" and "Please check the model of your router." The Wifi light on the router does not turn on (it is switched on). I'm stuck and don't know what to do! I use this router in a home office with multiple wifi users.
Can I run two networks, ie 192.168.1.xxx & 192.168.2.xxx, on the same switches. Certain PCs on the network will be set up for .
1 and others .
2. Each network would have its own router. I know I can't have DHCP on both routers,
if i give gateway of one as ip address of another and vice versa? both are directly connected and u cant use hub, switch,router...

View 1 Replies View RelatedSo far we add any router in the existing network simply by disabling DHCP server, and adding LAN ip for that. We don't add WAN detail at all in the additional routers. And plug one cable from main network to the LAN port of the additional routers.So we basically use that additional routers only as a access point for WIFI.But what I wonder is if it's possible for me to use the additional routers with the same feature as of the main routers i.e. Enabling DHCP server so that it too can give its own DHCP ip address.

View 2 Replies View RelatedI just tried replacing a cheap domestic router/switch with an RVS4000 V2 on our work network. This has a WAN connection to a cable modem for internet access via a dynamic IP address.
When I first connected the RVS4000 it got a WAN ip address via DHCP of 192.168.100.11. This is the type of IP address we get when there is an upstream problem with our ISPs cable network, and sure enough we had no internet access. The RVS4000 was set to use DHCP on the WAN interface. So I logged a support call with our ISP but they said there were no problems at their end.
I then swapped the RVS4000 out for the original router. This worked fine and got a WAN DHCP address of 77.xxx.yyy.zzz as it should. Swapped back to the RVS4000 and back to the same problem of getting a 192.168... address.
So, I downloaded the latest firmware from Cisco, which was V2.0.3.2 and flashed the RVS4000.
I then tried again connecting the RVS4000 to the cable modem but this time it would not get any WAN DHCP address at all. On the Status/Gateway page of the web interface it said that the WAN interface was down. However, on the front panel there was a yellow light indicating a live connection on the internet port.
I have a customer using a RVS4000, DHCP is enabled; the unit is set as gateway but there are no DHCP address assingments coming from the router.
View 2 Replies View RelatedI have a Cisco RV220W router (firmware version 1.0.4.17).
I would like to have two separate networks with the following specifications:
Netwrork1: address range for the network is 192.168.0.1-254. All devices should be able to reach eachother within this network and connect to the internet either on LAN or through Wifi. From this network I should also be able to reach the device management page of the router. Also the devices should get the ip addresses throgh DHCP.
Network2: address range for the network is 192.168.5.1-254. All devices within this network should not be able to reach the devices in network1. All devices on this network should reach the internet through Wifi only. Device management page should not be available on this network.
I have configured the router as shown in the attached screenshots but the problem is that in Network2, devices get IPs from the 192.168.0.1-254 range and not from the 192.168.5.1-254 range. Also there is no internet on these either.
I have Cisco router RV082 and I need to set up in this way. There should be two sunb nets.. each should have it´s own DHCP and each sub net should work in different external IP.. (one Internet port a and second DMZ/internet port)
Is it possible to set up?
What I'm trying to go for is to make a Static IP so that I can forward my ports in order to play certain games. I have had my ports forwarded at one time with a different ISP (in the same area), however they used cable and the company I'm with now uses DSL. The company "Hawaiian Telcom" has provided me with a Motorola 2210 modem/router. I have had trouble trying to create a static IP with this router so (sorry if this was a stupid move) I decided to buy a linksys router to try to port forward with that. When my ports were forwarded with the previous ISP I was using a linksys router then. The now aged linksys router was replaced due to it getting wet, but that's besides the point
