i am gonna using Peplink Manage 580 which support 5 WAN ports.because my country ISP just provide max 20Mbps internet service to business. that's why i want a load balancer that support 5 WAN ports.i plan to use 5 line which is 20Mbps each and connect to the 5 WAN ports.after connect to Peplink balancer, there is only 1 Gigabit LAN port to let me to connect to the switch.
And i need a at least 40 port of switch which all the 40 LAN cable will connect to TP-link AP.mean that all my client is using WIFI to access to the network. And i don't have much knowledge about networking, so i wish to use and unmanaged switch which able to handle 400-700 clients.any plug and play unmanaged network switch (at least 40 port) introduce?
Please find attached a simple BYOD/ISE document I uploaded to kick start my new Wireless setup. Its all configured on my ISE sever and Controller as per doc.My setup:
-3600 AP's
-Internal 5508 Controller
-DMZ 5508 Controller (acts as a DHCP server for wireless clients)
Controllers have established connectivity (mobility acnhors), as a client I can connect fine to my new SSID get a DHCP IP address back from DMZ WLC and at the moment can connect out to the Internet fine (using no WLAN Security as a test). So this part is working.I have now followed the document configured ISE, enabled AAA on the Internal WLC only and used the AAA override setting on WLAN as in the attached document.I connect to SSID expecting to be redirected to my ISE Guest Portal, nothing happens other than connecting to Internet WebPages.My question is, if I have followed this document correctly why is the Internal WLC not redirecting client requests to ISE, is this because my mobility anchors need to be re-configured, perhaps the AAA/ISE config needs to be applied to my DMZ WLC not internal WLC?
I would prefer the Internal WLC to redirect the login to ISE, doesn't make sense to traverse through the DMZ Firewall onto DMZ WLC back into the Internal Network again to the ISE to authenticate.Or am I missing something additionally to this document to make sure clients are directed to the ISE Guest portal login.
I'm using Cisco VPN client 5.0.7 and Cisco ASA 5510 (7.4 and 8.4.2) VPN RAS solution. Clients are authenticated using certificates and AAA RADIUS (ACS 3.3) and AD.Each time, when client connects, ASA issues 2 RADIUS requests, first - correct one which is successfully authenticated by ACS and immediately - second which always fails. I couldn't find any information related to this strange behaivor. "Double authentication" feature (most likeable to its name) is accessible only to Anyconnect clients which we don't use. When I'm authenicated using group password, there is only one RADIUS request.What is the source of such behavior?The negative impact is that my logs are filled with spurious failed auth attempts, and users are incrementig failed attemps counter in AD.

we are running 43 Cisco AIR-AP1252G-A-K9 wireless access points using POE in our facility. These are connected to Cisco switches in various locations throughout the warehouse. I have read many varying opinions on this matter some say do reboot some say never. Do these access points and switches need to be reset on a routine basis to insure reliability and performance?

I have a ISR 891 (no-wifi) router that I have been using on a 20Mbps x 20Mbps fiber circuit. It was been performing just fine. I am upgrading the curcuit to 50Mbps x 50Mbps soon, and I wanted to check if this router can handle that much load.
I don't do anything fancy with the router, just plain old routing (I have a firewall behind it).
Do you think the 891 can handle 50Mbps up/down, and if not what would you recommend for this new setup of 50x50Mbps.
I have read that the cisco 1841 can handle up to 100 VPN tunnels by default. Can this IOS version handle SSL VPN tunnels as well?

View 3 Replies View RelatedOur IPS has given us a second range of IPs as we were running out. Unfortunately, they can only give us two non overlapping range. I am running two ASA 5520 in fail over to handle our traffic but I don't know the best way to use both external ranges. This is not a failover scenario -- and I need outward facing servers on both ranges. It is adventageous to us to keep the two external subnets separating two of our operations so we don't want to bring everything into one subnet (long story).I have one NIC designated outside that will need to cater for both wans. As there are two subnet there are two gateways. How do I keep the traffic on track?

View 4 Replies View RelatedThis is only a small portion of our network but my question is, can these 1841 routers handle a 45Meg connection? I thought these routers were designed for T1/E1 type speeds. I know I saw a router performance document somewhere that showed 1841's could handle 38.4MB of traffic and that is only with routing turned on. If anything else is enabled, like access lists, NetFlow or whatever, that number will decrease because of the capacity of the router. Am I correct in these statements? Any document or anything else that shows performance of these routers?
View 14 Replies View RelatedWe have a problem with NLB on a SG500-28P which is a major issue for us.
I am investigating a problem together with Microsoft Support about a download/upload performance issue with a Microsoft Forefront TMG array which is connected to a single SG300-28P. Àpparently this issue exist on every NLB array we implement. I am now at the point we asume the SG500-28P does not handle NLB in unicast mode very well.
We have a network topology as shown below:Please note the actual public IP Addresses are hidden and the internal IP Addresses are diffrent, for security reasons.
Our SG500-28P is configure in L3 mode. It hosts three subnets you see above. The two TMG servers are configured with NLB (in unicast mode) on the Internal Network and External Network interface. It is connected to the internet and our internal network. These TMG Servers are in fact Edge Servers. Our other servers and client are in a different VLAN. The default gateway flows through this NLB Cluster [10.250.0.254].
Problem: When a client uses its default to connect to the internet the performance is very and very slow. With an internet connection of 10/10 we get 10/2. With an internet connection 100/100 we only get 7/1!.
Now we have tried everyting we can imagine. I can't write down all, because that would be a lot. One thing is worth notice; When we move the client to the same VLAN as the NLB Cluster and the client uses 10.250.0.1 as its default gateway, the problem still exists. But... when the client uses 10.250.0.254 as its default gateway the performance is outstanding 95/95! Apparently if traffic for the NLB Cluster is routed through the SG300-28P the performance drops like a rock.
I have never seen this before with SG300 series switches, although this environment is different. Normally I would configure NLB in multicast mode. But the switch does not allow to add static ARP entries for multicast MAC Addresses.I know NLB in unicast mode introduces switch flooding and such. But why does the SG500 not handle this right? Is there anything I can do about it?

View 3 Replies View RelatedSo a BT home hub is a very cheap router, so it seems. And - if you connect a quite a lot of eq to this router, it starts crashing. "It can't handle the traffic.". But what does that mean? Why can it handle the traffic for a while and after a few days it can't anymore. And lets say - some of the eq doesn't really work on the external network, it works on the internal network, and it doesn't need the internet to work for proper functionality. So - what is important then? Which specifications are the important ones?

View 4 Replies View RelatedWe have a 25Mbit connection comming in through a cable in the basement, going through a modem that is connected to a RVS4000 small buisness router on the first floor, that acts as the single NAT. Connected to that in parallel we have 4 wireless b/g or b/g/n routers of various cisco/linksys models, one for each floor, each with DHCP disabled.Over the last few months there have been some issues with the router and I'm curious if there is anything that can be done to solve them.The firmware of the router is the latest at the time of this writing, V2.0.2.7
1. The router will occasionally lock up and completely stop responding to DNS requests. Attempting to open a website will result in browsers giving their standard 'DNS Lookup Failure' messages. The router will also become completely non-responsive when trying to access it via its IP address (standard 192.168.1.1). No username/password dialog appears.However oddly enough IRC and other chats like skype will still work fine.Restoring Factory settings has not worked. This issue has gotten to the point where this happens about once a day. Restarting the router will fix the issue. While I think the issue may sometimes resolve itself, it could also just be one of the other people in the house restarting it manually.I'm assuming that the router is to blame here and not the cable modem in the basement or the DNS server of our ISP, mostly due to the fact that the router becomes unresponsive and won't let me log in as admin when this happens. also restarting the router, not the modem, seems to fix the issue.
2. The router's log is always empty Specifically I have enabled 'Output' and 'Local Log' as you can see here:
3. Issues with some people hogging bandwidth With 25 people and a 25Mbit connection each person in the house should effectively get about 125KB/s of download speed, especially since not everyone is always using bandwidth. However it can happen where one person is, often without knowing it, hogging a large chunk of bandwidth and slowing the network down for everyone, such as downloading multiple large files from different sites, streaming high-quality video, etc.I would like to know if any of the following might be possible to do with this router: See the bandwidth usage per individual MAC or IP address on the network over timeLimit the amount of bandwidth a specific MAC or IP address can use. Make the distribution of bandwidth more fair when a few people are using far more of it than other people.
I have at times resorted to limiting P2P via IPS in the past, and of-course that does work somewhat, but that's not ideal. I'd much rather just know who is doing it, and specifically by how much they are slowing other people down. While the IPS page will list the IP addresses of those trying to use P2P when it's disabled, there is no way for me to really quantify how much bandwidth they'd be using otherwise, and this doesn't at all include things straight-up HTTP downloads.In any case, this router should easily be able to handle ~25 simultaneous connections, right? Are there any settings that I should make sure to enable or set to distribute bandwidth more fairly, given the setup we have?
4. The IPS report chart is not readable.This is a bit of a nit-pick, but the IPS report chart is basically not readable because the colors used in the key are identical in color. Can you tell the difference between the colors of 'Network Traffic' and 'Attack Counts' in the key at the top? They could have used any two colors that are at least somewhat distinguishable, even light grey and dark grey would have been better, not magenta and another magenta.
We have an 1140N AP connected to a switch and our "network partner" controls the router and will hand out DHCP and do the NAT for this WLAN. How can I configure the AP to forward DCHP requests through.
I have WPA2 PSK (TKIP) setup and the client is able to authenticate however we fail to get an address. In this case the Ethernet interface was left alone so it has the default config and it gets a DHCP address fine. How can I configure this AP to enable the rest of the WiFI clients to get an IP?
I am using ACS5.1 connected to WLC (v7.x) and frequently see host auth requests in the ACS logs. I am not interested in seeing host auth requests at all. Is there anyway just to ignore these.The issue is that these will always fail. If I enable the lock out facility within WLC and a host continually tries to auth the WLC will lock-out that mac address meaning that when the user is ready to connect with their own credentials they are unable to as the WLC is blocking that mac address from connecting to the wireless network.I tried disabling the 'process host lookup' option, but this apparently only changes the type of request to appear like a standard PAP auth request which again fails, filling up my RADIUS logs and stopping me from enabling the WLC lookout feature.So, as I say, I want to simply ignore host requests. I have no control over the end points so am unable to go and update config etc of these devices.
View 4 Replies View RelatedI'm working on a project where a wi-fi client is tracked and located using RADIUS authentication requests.

I have a bandwidth-intensive video conferencing device connected to a router. I have forwarded all the necessary ports to the device (and I have even tried DMZ) but the device is unable to connect to some servers due to "NAT issues". The device uses lots of ports simultaneously to connect and I am wondering maybe possibly the router can not handle the number of open ports. The ISP only blocks port 25 which the device does not use. Could it be that the ISP limits the number of ports that are in use? Or maybe the ISP limits the amount of bandwidth that can pass through certain ports?
