• PSR 527W - external WAN ping port

  Hello

  As a test of raw it is convenient for us to external ping tne WAN port on the SRP 527W, gives us a quick idea of the question of if it will respond.

  Can someone advise how we configure the SRP 527W for this purpose? FYI, we have the inbulit RPS firewall is turned on.

  See you soon,.

• Could not ping router RV042G public Internet address when it is after spending a SG200-08

  I use the optical fiber Singtel broadband server. I installed a SG200-08 for UNTAG VLAN to port 2 and connect the port to port RV042G WAN 1. It works very well with a public IP address. Access to Internet is very well to router LAN ports.

  However, I try ping on the public IP address of RV042G of the internet, I could not reach him. Everything what I'm missing in configuration SG200-08?

• using wan-> wrt54g-> wan-> cant (static ip) ping a pc

  I've set up my wrt54g as point of wireless access, disabled the dhcp, and he ran to a pc wireless using a static ip address.  Computer gets Internet then I guess that I got everything right, but I need this pc to be available online, so I was wondering what security issues are prventing me ping my pc from another network.

  My departures from private network through a phone system my router what a wrt54g set up as a switch (NOT a router, so I know it's possible) before procceding to, another switch, computers... and I can ping this network very well static ip.

• General failure on Ping and TraceRT by WAN IP for 15 minutes after startup

  My Windows 7 64 of Profession will expose this problem.

  After startup, it cannot access anything whatsoever outside the local network.  I can ping, DRC and usually access anything whatsoever on the local network, including the router.  But trying to access what anyone outside the LAN does not work.

  Ping Returns the Timeout on the first response, and then general of failure for the other three.

  Tracert immediately returns a general failure

  I am ping IP address, no domain name, is not a DNS problem.

  After 15 minutes or, the problem resolves, and starting the machine works fine.

  Occasionally (once a day or more), it will return to the problem of General failure for 15 minutes, then return to normal.

  The problem does not occur in safe mode with network.

  The problem occurs whether the user is logged on the machine.

  I have disabled the Windows Firewall to try to resolve, without success.

  I also installed McAfee.

  Thanks for any help that anyone can provide.

  CP71

  I would start by removing McAfee and using MSE at least to test.  You can not just disable McAfee, it should be removed and he is known for this type of problem.

  McAffe often contributes to BSOD

  
  

  I remove and replace it with Microsoft Security Essentials

• Ping local IP devices

  Is it possible to Ping connected local IP addresses on different VLANS / subnets connected to the LAN, for example (192.168.0.5) ports, since the Web Interface of FVS336Gv2 when you're connected remotely? This would be very useful to try to solve the problems of local LAN if for any reason a peripheral LAN has been declared inadmissible. I know that the command ping WAN is possible through ports WAN 1 and 2.

  I don't see the "acceptable Solution" button anywhere on this forum, where is he?

• Access WAN LRT214

  Hello

  Just got my LRT214 to replace my old Juniper SSG5.

  The problem is that I can't get any access internet of the LRT214, all the settings are default, obtain an IP automatically by the ISP that works and I can ping the ISP DNS and GW, firewall rules are default and I tried to disable the Block WAN requests.

  Router in Bridge mode.

  Is there something I'm missing here?

  Make sure that the LRT running the latest firmware. If you download a new firmware do a reset to factory default and reconfigure from scratch.

  Post back if you can't make a Web site yet.

  Weird that you can ping the ISP GW and DNS, but does not go beyond the Gulf war.

• BEFSR41 v. 1 - do not get IP WAN, updated firmware to update

  I can get into the setup on the web.

  I can ping.

  ipconfig indicates that the LAN IP address is correct (192.168.1.1).

  All lights are light up properly.

  My internet connection works correctly (i.e. without the router).

  I've upgraded to the latest firmware (for this version of the router which is v.1, yes it's old).

  "But... under the tab"Status"in the setup, when I type"Release DHCP", then on DHCP renew," the WAN IP address is 0.0.0.0.  How can I force this thing to look for an IP address?

  Just can not know what does not work!

  Any ideas?  Thank you!!!

  (Mod Note: edited title)

  Assuming that you have a good ethernet cable between your BEFSR41 and router upstream (ADSL "modem" or "cable modem"), I guess the router upstream ISP (ADSL "modem" or "cable modem") is looking for a particular MAC address and is to remember your computer (since you've tried things wihtout the BEFSR41).  You have two choices.

  (1) turn off the router upstream (ADSL "modem" or "cable modem"), turn off the BEFSR41, wait a full minute, switch on the router upstream (ADSL "modem" or "cable modem"), let it resync to the line (takes a minute or two), then turn on the BEFSR41, see if it receives an IP address.

  If no, then try

  (2) to clone the MAC address of your computer on the WAN interface, repeat step 1.

• WRT160NL WAN ICMP responses

  Hello, I just bought a WRT160NL and im noticing that my WAN ip's ping'able is possible to disable ICMP responses on the WAN interface.

  Thank you!

  Hmmm...  Are you ping command from a device on the local network / wireless or in fact of the Internet / WAN side?

  I tried rattling from the outside and the setting works correctly as described.

  Ping from the inside always gets responses regardless of the setting.

• WRT54GL DROPS WAN

  Got a wrt54gl with tomato 1.23. He abandoned the WAN (cable modem) connection when the modem itself abandoned the connection for some reason; However after the modem comes back online and tomato shows in his page with the WAN connection as 'connected', you still cannot browse the internet. I know that the modem is good because if I connect directly to a computer, I CAN browse AND if I get (off ramp exit/Activ) powercycle the router, things return to normal. I can reproduce the problem by feeding and turn on the modem, which turns into exactly the same results, tomato showing the WAN that plugged in, but with the navigation impossible.

  I've been breaking my head about that person, here is some of the things I've tried:

  -With the help of different routers, I have 4 wrt54gl, some more recent that other, newer is fresh out of the box.

  -Clear NVRAM memory, doing resets hard.

  -The WAN connection is DHCP, tried to "trick" the router static IP, but without being able to navigate.

  -Tried checking the ARP tables, routing tables, ifconfig vlan0 downs and UPS (upon entering the router via ssh). Does not work although the paintings look like exactly the same before and after I have to reproduce the problem.

  -Cannot ping the gateway given by DHCP, even though the routing tables show the path to him.

  -Tried iptables f thorugh the console of the router, no nothing.

  -Tried the firmware linksys of origin, with the same results.

  N ' use is not apps torrent or something like that, just good old web navigation.

  Here is the log of routers (to this day).

  Now I have reduced to problems of communication between the modem and the router WHEN the modem disconnects, for some reason, worth mentioning that I CAN see the modem from the local network by going to its web interface, I can't use internet.

  Please help me on this one.

  Yes, Googling, it (and agree with you) I found that there is a timing issue with this SPECIFIC router, but it is not more than that.

  In any case, I found a solution to:

  http://victek.is-a-geek.com/REPOSITORIOS/Linksys/firmware/tomato/scripts/

  I used the script gateway2 to basically restart the wan (instead of the router itself) when the gateway does not respond to the ping command. I put this in a chron job every minute. It works, but it's not elegant.

  Well, I hope that the most recent routers do not have this problem. I'm waiting for 802.11n to get out (like not really rough). I hope that will be promptly accompanied by openwrt or tomato.

  Out of the object, if the sync problem is hardware related (because I guess it is) how could it not be fixed with open firmware? These 54 were long enough.

• ICMP followed WAN interfaces

  Hello - I am checking this product so I'm new on how it works. There may be an easy way to do what I'm looking for, but I don't see the hand.

  I added my remote routers using their IP address private - they're all available on DMVPN. Some of these routers have dual ISP, so I need to know if one of these is inaccessible via ICMP. I don't see a way to easily monitor ICMP of these interfaces, so I don't know when they are low. The interface itself is in place because it is always connected to the device of ESL premise, but it is not in the way of traffic. My router automatically detects and switches the tunnel to the backup interface, but I need to know what either of the ports WAN is down so I can follow with ESL. Of course, that I can just add each device 2 or 3 times using his IP different but that is a little more dirty I prefer.

  Is there someone doing something similar?

  Thank you very much for your help!

  Hello

  You can discover the router with the IP address you want to ping. You can do this as often as you want, which means that on a router with multiple IP, we can see devices, so you can get metrics on each IP address. You can alert out of a condition of ping response, which could inform you when it does not ping in a given period of time. Or, you can set an alert that fires when the traffic falls below a threshold... and trigger the alert.

  Thank you

• How to choose right for the WAN Interface MTU size?

  Hello

  I would like to know How to determine the right size MTU to set in the properties of the WAN interface (in my case, NSA appliances).

  First of all. I noticed that with SonicOS Enhanced 5.9.x, there is a Tool of diagnosis called PMTU discovery:

  

  This tool is not available with SonicOS Enhanced 5.8.x.

  I guess using this built-in tool is a way to determine the right MTU size to apply.

  Second, for SonicOS versions that do not have this tool and to understand just how to manually determine the size MTU, I would like to know what is the method to follow.

  On the Internet, I found this method by using the ping-f-l command. Once you have determined the largest possible packet size, it ask you to Add 28 to that number and you get the MTU size to define the interface.

  Case study:

  In my business, there are 2 sites: 1 in China and 1 in South Korea. Both have a firewall SonicWALL NSA.

  To determine the MTU size that is applicable from the Chinese site, I get the same results with the 2 methods mentioned above.

  With the help of the PMTU discovery:

  I get 2 IPs: 8.8.8.8 and the Korean FW IP WAN. I get the same result: 1500.

  

  

  However, I noticed that the MTU size should be set to its maximum (1500) of size on the properties of the interface WAN for this test to work properly. Indeed, when I put in 1404 to test, PMTU discovery find 1404 such as MTU size:

  

  

  With the help of ping - f - l:

  When you use the ping with FW Korea WAN IP method, I found 1472 as the maximum packet size:

  

  According to the method I've read on the Internet, adding 28 will make me a MTU of 1500, same size as the PMTU discovery method.

  My question is: can you confirm that these 2 methods are correct determine the MTU size to set the WAN interface? Especially the one with the ping command? If not, how do?

  Thanks in advance for your comments.

  I can tell you that as technicians, we use the way to CMD line to adjust the MTU on WAN interfaces. We saw this as a number to work with.

  Thank you

• Cisco 881 can ping internet but computers behind the router cannot
