The unit is configured as internet gateway. 4 NAT ports are active. When firewall disabled all works fine. When firewall enabled I do get connection lost at random interval. In firewall only 4 rules added to the default 3 rules. The added rules are:
1/ permit 192.168.1.22 port 25 to any 2/ permit 192.168.1.27 port 25 to any 3/ permit 192.168.1.10 port 25 to any 4/ deny any port 25 to any
I do get at random times connection lost when navigating with windows explorer on a PC with IP 192.168.1.x to a share on a PC with IP 172.25.152.74. The same happens when copying files. Sometimes it works, later it fails or reties are needed. When the firewall is switched off all runs fine.
Ping from 192.168.1.x to 172.25.152.74 allways give a <1ms response
Is there a RV082 perfomance problem or do I have a configuration problem?
I have a 3560 POE that will no longer boot and I am not able to load a fresh copy of software onto it. It appears that it has lost all data. When I attempt to TFTP a new IOS, I receive that following error:
Transfer cancelled by remote system
I have tried using dir flash: to see what is contained in the flash directory but I receive the below message:
unable to stat flash/: no such device
I am stuck in rommon mode so when I do switch: dir command, I don't even see flash as being a filesystem. The below list are the only systems registered.
After not seeming to be able to save any configurations in 12.2(25)FX, I thought an upgrade would work since it said it didn't recognize my browser or OS but let me continue. I was able to see everything just couldn't save changes.
I updated to 15.0(1)SE3 and everything seemed to be going well. Tried to log back in HTTP (have not set n IP yet since it is still at my house... DHCP seems to be working) and I get a user/password screen that says level_15_access and it won't let me in.
Attempts to log in terminal have been unsuccessful. I can log in my dell switch which I am replacing and my APC units terminal just fine using USB to serial and Ubuntu.
I tried cisco as a password, user and password, admin, administrator no luck.
What is the best way to resolve this, is there a sure fire windows serial program or settings I should use in linux (currently 9600,8,N,1) to connect? I have looked through manuals till I am blue in the face.
I have two 3560s that i would like to upgrade. But first i would like to make -absolutely- sure i dont wind up in a situation where i have to roll back over a console connection.to the day i still cant understand why oh why someone removed (or chose not to implement it everywhere) tftpdnld from rommon ;)
I start configuring Cisco 2821 router for multicast . First short description and attached sheme explanation. Let we say I have small network with 100 users. One router and Cisco switch 3560. Two VLAN’s, one for data another for multicast. Data from internet works fine but now I want to connect multicast servers (or source of more multicast streams) from another subnet. Router have three interfaces.I expect there should be no problems with multicast configuration, but unfortunately it is not like I expect. What I did ?
i have a cisco 1900 series router from the isp and we connect it the our router the rv042 small biz, and we have here a cisco catalyst 2950 switch with just default configuration connected to the hosts.
my problem is from time to time that the connection is lost there is no connection with the router and the only solution is to turn off and on the cisco 1900 router and the connection will be back.
do we need to configure the routers and switches? what do you need to configure?
i am not sure if this is something with my DHCP setup or not, but it certainly seems to be the culprit. I am running a 3560G and using it as DHCP and to do V LAN routing (Geiger protocol). I have 10 pools configured with a few static addresses per pool. Now to get down to the problem. I have a computer (and this problem seems to be a gremlin as it changes what computer is affected quite often) that will connect, get its IP, immediately disconnect, then send out a DHCP req again. The computer has a static assignment in the pool, and for the brief second that it connects, it gets the right address. If i move the computer to another v lan, all works right. If i delete the static entry it will get an address in the right v lan no problem. The command i have been using to add static entries is:
That seems to have been working on all my static routes except for a bank of computers in vlan3. I have went as far as to delete the pool and recreate it, heck i even recreated the v lan and i am still having issues. Below are some snippets of the running config for review.
The DHCP Pool for the affected LAN: ip dhcp pool Dev3 network 192.168.3.0 255.255.255.0 boot file bootx86wdsnbp.com next-server 192.168.1.78 dns- server 192.168.1.8 192.168.1.78 [Code] .....
I have been reading for awhile now on all the Cisco forums on the 3560 and shaping egress traffic but I wanted to verify my thoughts on this. I have 3560 that connects to the ISP that is policing at 10Megs, I want to shape my egress traffic going to the ISP, I do not want to provided QOS to any specific traffic type but only shape all traffic outbound. Will my config below shape "all" egress traffic going to the ISP on the 3560, on a port that is physically connect at 100Meg Full duplex?
int gi0/1 srr-queue bandwidth shape 40 40 40 40
I gathered these numbers using the formula of 100* 1/weight, which would equal 2.5 and if each queue has 2.5 meg that would = 10Meg. However another concern is that I don't think I have the full 100Meg on the interface to use (correct?)
I've been trying to set my IP to a static IP so I can host servers for a few different games and every time I change the IPV4 settings my internet stops working and when I troubleshoot it says "DHCP Not enabled for local area connection.".
My WAP4410N is configured with 4 seperate SSIDs. Two of the SSID status are showing "Enabled". The other 2 are shown as "Connected". The one that are showing as Enabled are not receiving any packets. Devices connected to the SSID that shows "Enabled" are unable to connect to the network. Any one else encountered similar issues before? This issue just surfaced few hours ago. The device has been using for around 2-3 years with minimal issues.
I was trying to port fwd my RDP and then I ended up getting side tracted and changed my routers password [URL] it would cause my router to stop working. I know my adapter is fine, because I can connect to the internet via wired connection. My wifi DHCP is not enabled however and I have no clue on how to enable it.
Here is the settings from ipconfig/all

I have a power conncet 6224 with routing enabled with several VLANs setup.VLAN Database: 6,8,10,90-254VLAN 6 is our management vlan10 is for our core network services (DNS, Domain, Exchange etc)90-254 are isolated vlans.What I need to accomplish is to prevent vlans 90-254 from communicating with each other and only allow communication to VLAN 10 and the internet. All internet firewall work will be handled by our Sonicwall. [code]
When I have both 2,4 and 5,0 GHz band enabled on the E4200 router my PC (WMP600N-PCI adapter) has max. 130Mbps.When I enable only the 5,0 GHz band it has a speed of 270Mbps.The same speed issue with my Dell laptop.Router and PCI adapter are new (3 days old) and both have the latest firmware.Both PC and laptop are running on W7.how to increase the speed with both bands enabled?
I have repaired tcp/ip stack and winsock by command prompt. When I check my ipconfig /all there are alot of things not enabled and default gateway with no address etc... I checked my advanced setting and dhcp auto obtain is enabled. When I try to release and renew ipconfig the addresses are missing and when I renew, it's completely missing.

We have just received a new 3750X-12S-S to put onto our existing network but I am having a few issues getting this switch working correctly. For this post, the permenant license is not activating/applying, switch boot up gives the following errors:
I have a customer who just bought a pair of N5K and wanted to replace his current HP E3800 as Core. He wants to use the 4 x stacked HP E3800 connect back to the N5K. Will I be able to utilize VPC through a bundled 2 or 4 x 10G (40G) connection (10 or 20G on 1 switch, and 10 or 20G on another switch) from the stacked HP E3800s to the N5548s? I know you can do that with Cisco 3750s.
Document at url... is quite interesting,One of these goes about the behavior of a switch (2960-S and 3750G) when QoS is not enabled vs the one when QoS is simply enabled with "mls qos".What additional commands, beside "mls qos", would be needed so as to simulate as accurately as possible the switch's behavior when QoS is not enabled?
I had problem with IP conflit address from cisco router 2911 , all the time the router respond with ARP reply (duplicate use of IP : x.y.z.t with the same Mac Address ) and the IP subject of conflit dosen't appear in any router's interfaces configuration (basic configuration without dhcp) ,the problem was solved problem when I desactivete proxy arp but I can't understand this behavior , why arp proxy respond to all IP address with same Mac even the IP dosen't exist in router ?
We are seeing output drops on a C3560 switchport, this port does not have QoS enabled -- application does not need special qos treatment, as long as packets are not droppd, so I suppose all traffic will share the same queue? then how should I read the output of "show platform port-asic stats drop" which indicates that it is queue 3 weight 2 drop? I am wondering what is the best way to fix this? enable mls QoS and increase queue 3 bandwidth share on this interface or just increase the output queue depth?
switch#sh mls qos interface gi0/1 GigabitEthernet0/1 QoS is disabled. When QoS is enabled, following settings will be applied trust state: not trusted
I have enabled syslog on my Cisco 2960S swtich as shown below -
-logging facility local6 -logging host 10.11.12.122 transport tcp port 514
I have sent the port to TCP since that is what is configured on the SYSLOG server which is a CENTOS 5.8, running rsyslogd.I have tested the rsyslogd locally and it work.However i want to send any and all log messages in the buffer to my syslog server and it is not working.there is no firewall on the CENTOS and the ASA firewall filter is enabled for outgoing traffic.
I would like to apply a policy-based route on one of our L3 switches (Cisco 3750) to change the next-hop of a couple of servers only. The VLAN where those servers reside got WCCP enabled on it. When I want to apply the route-policy to that VLAN interface it doesn't let me. When I try to apply the same policy to a VLAN interface without WCCP it does work. Is there any Cisco IOS limitations that would prevent me from doing that?
to play Xbox Live and use my computer at the same time and all of a sudden my connection would be lost. I eventually figured out that my laptops Wireless connection being lost was completely to blame on my Wired Xbox connecting to the internet.
I'm not working on a computer now. This is just a question of curiosity since I am still learning networking. I did a reinstall for someone. Once they brought their computer back home their Verizon DSL connection was not working. He could not Ping Google.com.
I had lost power to my apartment and when everything came back on everything was working as normal...until about an hour later when my internet connection was sporadic at best. I called the ISP and they confirmed that the modem is fine. My other computers can connect to it via ethernet cable and wifi so it doesn't appear to be the router.
When I try to ping anything it seems to time out randomly.. (ran "ping Yahoo! -t1" and let it go for a while..times out every 10 requests or so).
I swapped out the ethernet cable but the LEDs on the NIC are Orange(Amber) for both cables. The wifi on the computer works fine. I reinstalled the driver for the NIC.
