Cisco WAN :: Internet Interface Protection On ASR 10001 Router?

Apr 30, 2013

I want to provide some outside interface protection on an ASR 10001 router. The Internet facing interface is the ingress for all remote access home users that have created a DMVPN. I want to protect the network from the Internet but, at the same time protect against breaking the tunnels created from the home users.We are running EIGRP between the home users and the HQ router. How would you build the access-list applied to the outside interface and what protocols would you allow through?

Security / Firewalls :: Lose Internet Access Every Time Enable SPI Protection?

Aug 12, 2011

So, I have this router at home a WRT150N. I put in access restrictions so my siblings won't stray onto unwanted pages.I enabled SPI Firewall Protection and what do you know, it worked. The next day though, we didn't have an internet connection.I checked everything with the modem (power cycles, etc.) and then I tried the router. Upon disabling SPI Firewall Protection, the internet connection came back.I tested it yet again, to see if it really was the SPI. Enabled and bam, no internet access again. I made sure to select "Allow" in the Access Restrictions for "Internet access during selected days and hours" making sure also that "Everyday" and "24 Hours" are selected.Now my question is, what do I need to do in order to enable my Access Restrictions without having to lose internet connection via the SPI Firewall?

Cisco Switching/Routing :: Extending VPC Vlans Across Single Connected (into 7K) L2 Path?

Feb 19, 2012

Nexus infrastructure is pair of N7K switches, with dual homed 5K/2K devices connected, links use vPC. They want to extend vlan's from the 5K/2K side across a L2 path into another DC, this path is only connected into one of the N7K switches, call this 7K switch A.I'm concerned that packets from the 5K/2K side back to the remote DC could get dropped due to the vPC loop dectection process. If a packet from the 5K/2K side traverses the path into the same N7K (7K switch A) as the L2 extension, I dont see a problem. But, if the etherchannel load balance in the 5K sends traffic to the packet to N7K B, in order to get to the L2 path extension to the remote DC the packet gets forwarded across the vPC. My understanding is that this packet will get dropped by N7K A as its local L2 path to the remote DC is up, is this the case?I see a solution is to plug the L2 path into a 2K, but before I suggest this is my understanding of the loop detection process correct?

Cisco Firewall :: 65535 ASA - Port Scanning Protection Through Embryonic Limit Setup

Jul 1, 2011

url...I discovered that it would be possible to be protected from portscan, i mean when someone scan our nework/host from outside, the attacker will see all the 65535 ports as "open" (in that way it will be more difficult for an attacker to perform customized attacks...)So I have follow the setup in that link: policy-map global_policy class class-defaults set connection embryonic-conn-max 15 per-client-embryonic-max 3 service-policy global_policy global . The problem is that I don't have the exepected result..If i do a portscan over Internet from an external host to my hosts the portscan is successfully working and I can view my open ports...I have also tried to set this through a "match" in an access-list but without any sucess.

Cisco Wireless :: 4402 - Data Path Down Control Path Up

May 5, 2010

have just set up a WLC 4402 as a Guest WLAN controller on the DMZ of our network. I have successfully managed to get our internal controllers to connect to it, with the exception of 1. it says the control path is up but the data path is down. the other 14 controllers worked fine, and in testing the last one was OK but it is now not working properly. the 2 controllers can ping each other but just won't create the data tunnel. there is a firewall in the middle but that has been set up to allow traffic between the 2 groups of controllers to be unrestricted.
the internal controllers are 4404's and all controllers are running the same version of code.

Linksys Wireless Router :: WRT120N LAN Port 1 Flashing But Not Connected To Physical Port

Jun 24, 2012

I've been using a WRT120N on a local area connection.The WRT120N acts as a gateway and also to connect to the PPOE connection, via a bridged adsl modem.I've noticed that the LAN port 1 was flashing although the network cable was disconnected from the physical port. I've restarted a few times but to no avail as well. Ever since that, I've noticed that connection through cable are unstable and hard.Now, I'm not able to reset or upgrade the router's firmware.Is there any other way to be done so that I can get this router working as normal again.

Cisco LAN :: 1801 Unknown Protocol Drops On Connected Router Interface

Oct 28, 2008

I have a 1801 router connected to a 3550 switch with a regular 802.1q trunk, and I am curious as to what may be causing the unknown protocol drops on the connected router interface.
The switch is without any configuration at all except the following for the trunk configuration on the interface connecting to the router.
-interface FastEthernet0/1
-switchport trunk encapsulation dot1q
-switchport mode trunk
-Interface FastEthernet8
-switchport mode trunk
There is nothing connected to the switch other than the router so the dropped traffic must be originating from the switch itself.The unknown protocol drop counter on the router increments by one every 30 seconds, and I tried using a packet sniffer but nothing noticeble showed up.
I read elsewhere on these forums that it might be udld, but that is not enabled by default, and just to be sure I tried disabling it on the interface and as expected it said it was not enabled, so I am ruling that one out.I also read that it could be because the router is recieving traffic from other protocols than IP, but I do not see how it applies in this case.

what does a 3550 send every 30 seconds that my 1801 does not understand?Could it have something to do with STP?

Cisco :: 2800 Enable SNMP Discovery Through External Interface

May 28, 2012

I'm trying to add some 2800 series routers to our monitoring environment, but I can't get them discovered.
On the Mgmt Server I need to go through a "discovery" process to add the 2800 to the system. For this I target the internal interface ( i) but the discovery fails. I'm assuming the packets are getting dropped on the outside interface (e). I know SNMP is set up correctly and works as I had PRTG installed on a local box (p) for testing purposes.
The intention is to do the data gathering via a proxy agent (p), so enableing SNMP on the outside interface is not going to do me any good.What do I need to do to let those discovery packets pass through? At least temporarily?

Cisco WAN :: No Link On 1941 Router When Connected To Routed Port?

Aug 30, 2012

During an installation, we plugged a Ruckus wireless bridge (powered by a PoE injector) into G0/0 on the 1941.  The port status remained down/down.  We then tried connecting it to G0/1.  Again, the port status remained down/down.  We took another wireless bridge, plugged it into G0/0 and the port changed to up/up status within a few seconds.  The same happened when connected to G0/1.  Both ports are have speed/duplex set to auto/auto.We took the cable from the first wireless bridge and connected it a 3550 switch, the FastEthernet port went up/up.  We then took the cable and connected it to a switchport card (HWIC-4ESW) that was installed in the 1941 router.  The port came up/up.We connected to wireless bridge back to G0/0 in the 1941 and manually set the speed/duplex to 1000/full.  The link light on the router became illuminated after a few seconds but no console message was displayed (nor did any events appear in the log) and a "show int g0/0" showed the port status as down/down. This was could not be duplicated as this only happened one time The wireless bridges sit atop of a water tower and are connected each via a shielded ethernet cable.  The cable that we're having trouble with is cat5e STP and about 310feet in length.  I should note that we have not yet swapped the PoE injector but it seams to be functioning properly as power is getting to the wireless bridge and its accessible.  Also because if the wireless bridge for some reason didn't come back up after a power cycle it would potentially mean climbing the tower to perform a hard reset.  We tried another 1941 with same results however we have not tried another router model to rule out a potential platform issue.  Can you recommend any troubleshooting steps to determine why the port status of the gig interfaces on the 1941 don't come up?

Linksys Wireless Router :: WRT120N Disable SPI Firewall Protection And Anonymous Internet Request

Oct 14, 2009

I'm about fed up with with having this issue that no one can seem to solve. It dates back to when I owned a WRT54G router. I started experiencing random disconnects with the router, both wired and wireless. I only owned the router a year and figured it was going bad.
So I purchased this WRT120N router late August. Soon after I set the router up, low and behold the same problem started. I've called my ISP a couple occasions and they tell me that everything is fine from their end. I've spoken with Linksys tech support on 3 seperate occasions. I have changed the MTU to 3 different values and upgraded the firmware. The 2nd support tech suggested that I do those two things. To my surprise this worked for 2 or 3 weeks with no problem. The same problem started again just last night disconnecting intermittingly. I spoke with another support tech and they suggested that disable the SPI Firewall protection and Anonymous internet request. That did not work for the brief time I had this disabled.
More into the problem, when it disconnects the modem seems fine but the activity light on it stops as it should. The router itself appears to reboot, then when it comes back up the connection restores. What could possibly cause this? I currently have version 1.0.02.This is getting very frustrating and I am getting very near not using Linksys/Cisco products any longer.

Later i have connected another PC. The packets got dropped. But when i connected the original PC again, the packets flow started again.So, i have a doubt. Will the packet flow get establish, when the original PC is connected again to a port which is applied with port security violation "Restrict"?
