Cisco Routers :: WRVS4400N - ACL Rule(s) Causing Sever Slowdown?

Feb 24, 2012

I have a DSL line at work that we use to test external services provided to external users on our primary Internet circuit (Citrix, web applications, etc).  Because this DSL line is for testing only, we want to lock it down so the only destinations allowed through the firewall are our own IP spaces. 
 
I purchased a WRVS4400N for this purpose, thinking I could use the IP based ACL list to create these restrictions.  However, every time I try to create an ACL, the internet slows to a crawl, and many sites don't come up at all.  This occurs even if the ACL rule I add is a simple "allow any any" rule similar to the default rules.
 
Is this a known issue, or am I configuring something incorrectly?  Here's an example of a rule I'm using (IP not real):
 
Action     Service          Source Interface     Source     Destination                                   Time              Day
Allow      All Protocol     LAN                    ANY           1.2.3.0/255.255.255.240*             Any Time       Every Day  
 
I also get the problem with a simple allow from a single IP (mine) to any destination, without any other rules enabled.
 
implementation of the ACL ruleset on these routers?

Cisco :: LMS 3.2 Is Causing High CPU On Routers?

Sep 5, 2011

A customer reported that their router experienced spikes (high cpu utilization) every 4 hours and claims that it is caused by snmp polling of the Ciscoworks server.

The process SNMP engine is the process that causes these spikes .We think that the job responsible of this periodic high CPU utilization. It's called "Vrf Collector Job" and it's runnning every 4 hours.Below the result of show stack PID and show version

Cisco Routers :: Rv082 Dmz Rule Limitations

Apr 27, 2013

we have a RV082 and have the DMZ option enable for a range of IPs within the same subnet of WAN IP and this works great. I have another range of Public IPs from our ISP that is not in the same subnet of the WAN IP and do not see a way on the RV082 to include this 2nd bank of Public IPs in the DMZ. Our ISP internet feed plugs into the RV082 WAN port and we have a switch pulgged into the DMZ port of the RV082 that is used to connect the public devices in the current DMZ. Both banks of Public IPs from our ISP come over via the ISP internet feed plugged into the WAN Port. My question is, if I cannot configure a DMZ rule to allow this 2nd range of Public IPs to "travel" to the RV082 DMZ port.

Cisco Routers :: Rv082 Firewall Rule Not Working

Oct 14, 2011

i have a Cisco Rv082 with Firmware v4.0.4.02-tm (Jul 4 2011 13:30:56)I have configure WAN1 with a public IP and netmask 255.255.255.252. (Only one public IP in use) Internally the LAN is a 192.168.169.0/255.255.255.0.I need to add some rules like

Service: HTTP
Interface: WAN1
From: ANY
To: 192.168.169.2
 
But after rule configured the connection still not working, it only works when I add a port forwarding.For HTTP maybe port forwarding is OK, but other services I need to grant access to a specific public IP address, not to everyone. So I need the Firewall rule, but is not working, it always block the request. [code]

Cisco Routers :: RVS4000 WOL Rule Not Working From WAN (Internet)?

Oct 17, 2012

I picked up an RVS4000 V2 and configured a rule to forward a Magic Packet to an internal system to wake it from a sleep state. Everything was working fine until I update the firmware to v2.0.3.2. I know it's not the the computer as I can wake it from Sleep internally without any problems. One thing I noticed is that the static IP for the computer in Sleep state gets lost in the ARP/RARP Table though the NIC is configured to respond to ARP requests in Sleep.
 
Has anything changed in v2.0.3.2 that requires a different configuration to get Wake on Lan working externally?

My Setup is
 
Computer
P8Z68 Deluxe/Gen3 onboard Intel 82579V NIC
Wake on Magic Packet: ON
Respond to ARP/NS requests without waking system: ON
 RVS4000 V2 (v2.0.3.2)
Mode: Gateway

Cisco Switches :: Slowdown / Latency On SG 200-26P When Under Heavy IO

Apr 26, 2012

We used the SG 200-26P (firmware 1.1.1.8 ) as our main LAN switch. We have a few other 100Mb switches but our servers and nodes in our cluster are all on this switch. If you log onto a machine on one of the other 100Mb switches and then Remote Desktop to a virtual machine that is running off the SG 200-26P, and then copy say a large file (500Mb) your you will get major delays in the response time. For instance mouse clicks, screen paints, etc. Remote Desktop to a VM is unusable during this time period. This also happens for instance during backups when files are being copied from a machine to a VM. 
 
As mentioned the other switches are 100Mb switches from HP, a bit old.  I didn't change much in the setup of the SG 200-26P our of the box.  Jumbo frames is disabled, RSTP is enabled, with Flooding for BPDU handling.

Internet Slowdown And Random Disconnect

May 27, 2011

Recently I bought a new PC to replace an old laptop that I use in my bedroom. However, initially I couldn't pick up my downstairs router signal. So, I bought a new wireless network card and STILL didn't pick up any signal. I then purchased a Netgear WN200RPT and everything seemed to be ok while using that to repeat the signal up into my bedroom. Then, suddenly, it all stopped working. The WN200RPT would, although showing a full internet connection with no yellow ! or red x's, it would never ever load webpages. So, I removed it and put it back in its box. Then, for some unknown reason after a Windows 7 reinstall, my network card started picking up the signal from my home router and had a good speed and signal. This worked fine for a month or two before it started playing up again. It would randomly slow down and stop loading webpages, or completely lose the signal and show a red x, stating that no signals could be found. The strange thing is, all the other PCs in my house connect wirelessly fine, and so did the laptop that was in the same room as this PC. After a system restore, the internet started working again. Then it stopped. Another restore later, it works. Now it's intermittent again.

Cisco Routers :: RV220W Access Rule Reorder Broken?

Jul 24, 2012

I need to add some rules to block some attacks. I can add them fine but they get added to the end of the list. I try to re-order the rules to put them at the top and can not. I am using Internet Exploder 8 and I put a checkmark on the rule I want to move then click the reorder button. It takes me to a screen that shows 0 rules. I click the Back button and am back at the list of rules on that page. I am running the latest firmware which is from a year ago.

Cisco Routers :: RVS4000 - Format To Input Into ACL Rule Range

Feb 18, 2012

I have read through the manual. My question is what is the proper format to input into the ACL rule "Range"?  Would as an example work- 192.168.0.1 - 192.169.255.254? Will the range effectively work? Or does it have to be 192.168.0.0 - 192.169.255.255?

Cisco Routers :: RV042 Portforwarding Overrule Firewall Rule?

Nov 1, 2011

We have a setup where our e-mail server is hosted in-house.Our network is connected through a RV042 gateway. Port 25 is forwarded to our internal e-mail server.Our smtp service should be limited to receiving incomming connections only from 4 specific ip ranges which I set up in the firewall rules.The reason is that all smtp is managed and protected by an external anti-spam/vires provider.
 
However it looks like any computer is able to connect to our port 25 and be forwarded to our e-mail server.Does portforwarding overrule firewall rules - ie. you can not limit access with the firewall if you decide to port forward?Is this a "fixable" situation - or is the RV042 not built for handling this setup?

Cabling / Cards :: Sudden Network Slowdown?

Apr 3, 2012

Three days ago people started complaining that it seemed slow. It's supposed to be 100mbps fully switched, but I'm getting speeds of 2mbps - 12mbps (at most) between two workstations on the same switch (which is just insane). I did happen to notice on a couple of the Mac OS X machines that the send and receive errors are off the charts (50% - 80% error rate)!!! This seems a bit suspicious to me.

Cisco Routers :: WRVS4400N WAN Interface Down?

Jul 5, 2011

Right out of the box, the WRVS4400N [firmware v2.0.1.3] I just purchased says the WAN interface is DOWN; and it simply will not obtain an IP address from the Arris TM602G cable modem it is attached to. Internet still runs great on the old WRT54G. Is this WRVS4400 DOA? Or is there some arcane setting the quickstart guide overlooks? OR?

Cisco Routers :: How To Configure WRVS4400n

Dec 7, 2011

I'll just use the 4400n to provide DHCP to my two VLANs and then a new problem cropped up.  I am unable to add a default route to the 4400n's DHCP server.  It uses the 4400n's vlan IP as the default route.  What I'm trying to ultimately achieve is to configure the 4400n as an access point for our "private" network on vlan1 and also "guest" access to the internet on vlan2.

Cisco Routers :: WRVS4400N V2 - Setting Up VPN For Mac?

Mar 3, 2013

I'm having problems trying to establish a IP Sec tunnel from the office to home. All of our machines are Macs so I have been using the directions described in "How to create an IP Sec tunnel for MAC Clients, A QVPN alternative" but I still can't get it to work. My setup is as follows:
 
The office is connected to the outside world through a MODEM (Sagemcom 2864 Connection Hub). This MODEM is also a wireless router. It's DHCP server provides addresses 192.168.2.x.The WRVS4400N's WAN port is connected to one of the LAN ports on the MODEM. It's IP address from the MODEM is 192.168.2.x. The WRVS4400N provides addresses 192.168.21.x to devices connected to it.We have a DynDNS account and are using the DDNS client on the WRVS4400N router to connect to it.At home, we have a DIR-655 router with IP Sec Passthru enabled. The router provides IP addresses 192.168.1.x for all devices connected to it. I am fairly sure there are no issues with the router setup at home since I am able to VPN into the office of my full-time job without any problems. I have tried just about everything I can think of but have not been able to get this to work. setting up the Local and Remote Group Settings on the WRVS4400N and the IP address settings in IP Securitas?

Cisco Routers :: DNS On Modem Or WRVS4400n?

Sep 15, 2012

I have successfully got QuickVPN working from Windows 7 64bit into my WRVS4400n.  The router is sat behind another router/modem (Belkin) as the UK uses PPPoA and the WRVS4400n doesn't.So I set up DMZ and changed the DHCP to always allocate 10.x.x.2 on the Belkin which is the WAN side for the WRVS4400n as it is the only thing attached.I have now noticed, and I'm not sure whether it was the case before, that the DNS that the WRVS4400 is showing is the LAN address for the Belkin  Modem/Router (10.x.x.1), not 192.x.x.1 for the WRVS4400n itself.  I assumed setting the Static DNS 1 on the WRVS4400n would do it, but it didn't?When I connect into the network with QuickVPN, the computer names do not show even though I have selected the option in QuickVPN?

Cisco Routers :: WRVS4400N Cannot Browse Anything

Dec 16, 2012

Recently installed a WRVS4400N router on my home network. Prior to that I was using the wireless built into my FIOS router. I wanted something more secure so I went with the WRVS4400N. I turned off the FIOS wireless and am only using the cisco wireless.

Im having intermittent issues with the wireless. I have many things hooked up to my wireless including a HP printer and a Sonos system. Most of the time if I just open my ipad I cannot see anything else on my network including the printer. If I try to see the Sonos system can cannot, sometimes I can open the app on my iphone and then I can see it.

Sometimes I can see the printer and sometimes I cant. Sometimes when I do see it and then print to it, it will be gone before it even prints.
I don’t seem to have any issues thru the LAN connections.
 
Also, ive noticed that the wifi is much slower than the old FIOS box.
 
FYI, when I remove the cisco and fire back up the FIOS wifi I don’t have any problems at all at any time. And its much faster.
 
I have tried channel 6, 11 and auto. Also turned off IPC and still no change.
