Cisco :: How To Place A Switch Before Two Routers
Feb 16, 2013
I'm currently trying to setup a VPN to a Amazon instance but running into a few problems. My current setup is optimum lightpath into a windows 2003 server running ISA 2004 out the a switch handling several servers and laptops/desktops. To setup a VPN connection we purchased a Cisco 1941 IAS but having a problem running this through the ISA Firewall. I giving it a static address and porting it to a external address through ISA <opening UDP and the IPsec 50 and 5000> but nothing. Unles to get this to work I decided to just put a switch before the firewall plugging the optimum router into the switch and then plugging the VPN router and the ISA server in the switch so all the IAS doesn't have to run through the firewall <if I lost you be tell me>

I have an ASA 5510 that I want to connect to 2 isp (one of my private network uses the isp1, and all others the isp2). Excluding the 5510 does not accept PBR(policy based routing), i saw that you could put a router, like cisco 2811 in front of the ISP. my questions are : can i put a switch 3750 in place of the 2811 router? , I have vpn connections in isp1, this architecture is compatible?

I want a low cost solution router with 16 10/100 routed ports...The idea is to club 16 different segments on ofc to this router via media convertor and there will be dynamic protocols such as EIGRP or higher running between these segments.
The router needs to be security enabled...the equipments needs to be a router by defination (not a layer 3 switch)..As per my understanding there is limitation on number of HWIC-2 FE that can be put in ISR G2 series due to which I cannot reach that figure...
Kindly let me know if i can use SM-ES3-16-P in the place of HWIC-2FE for this kind of requirement.

I have been working nicely with an industrial scanner that runs on Linux, but the harddrive has become corrupted and I need to get it working again. The problem is that the main PCB has a realtek chip which I believe has the most basic webserver abilities that is used in the most basic way possible. To use it ARP commands were used to assign an IP address to the chips MAC address e.g. something like: arp -s 192.168.2.5 00-05-a4-00-a8-f8(the actual MAC address was lost along with the HD)So now I'm starting from scratch in XP, how do I find the MAC address in the first place?

I am looking to add remote sites that will authenticate with the Windows Server using VPN via Cisco rv042 routers in a gateway to gateway setup.My main concern is the placement of the server to the router and what would be considered best practice.In my mind, option 1 seems to be what I want - however, this would mean disconnecting the WAN feed to the server (my ip is static and tied into the MAC address of the server). While option 2 doesn't look right to me, it would leave the existing configurations in place which would minimize my downtime (I think)

I have a case that to minimize wireless signal into one room.Room has dimenitons 3 x 6 meters.But the signal should pass to other room.I have tried many scenarios but couldnt reach the result that i expect.First i have used a 3502 with external antenna ports , but no antenna attached to it.I have set up the maximum power level from TPC menu from controller , but it was more limited than i thought.I can only connect whenever i put Ap next to myself.Then i have used a 3602 with internal antennas.The reason i have picked 3602 is , it has the lowest gain 2.4GHz antenna attached to it.I reset TPC to minimum power level (5) , but as expected signal can be heard from two rooms from the AP is located.

We have a main office and 4 remote offices (only showing 1 remote office in the diagram). We are using GRE over IPSec VPNs to the remote offices which terminate on the 2811 router in the main office. We are using the 2811 as it is the only device that we have that can terminate GRE. The 2811 router is connected to the outside switch and is configured with a public IP address. We also have a ASA5510 in the main office which is connected in the same manner and is used for Web, e-mail traffic etc.Both the main office and remote offices have a 10Mbps Internet connection.
We have an issue with voice quality between sites as we are finding it difficult to control bandwidth utilization in the main office. When users in the main office download web content it can saturate the 10Mbps Internet connection causing voice quality issues. We have configured outbound shaping on the branch routers to make sure that aggregate inbound traffic from all branches to the main office does not saturate the link but we cannot control traffic from the Internet.I understand that controlling inbound traffic from the Internet is difficult without controlling QoS on the ISPs side. Is there any way that can reserve inbound bandwidth to ensure that web traffic does not impact voice? Also in this design, which is the best place to configure outbound QoS from the main office?

I have Network Magic Essentials and use a Linksys WRT54GS router. I just received a Cisco Linksys 2500 and assumed that it would be a breeze to set-up in place of the WRT54, so that I could gain faster internet and improved range. After about six hours of frustration trying to set it up, I am pulling my hair out! I live in a remote area near a lake, and our only option here is a
Wi-Fi signal beamed to our homes via an antenna, coax cable to a "radio" ( Alvarion BreezeAccess). This has always worked very well with the WRT54, but with with the Cisco 2500, I can get on my local network just fine, but I cannot get connected to the internet. I can disconnect the 2500, and reconnect the WRT54, and get right back on the internet.

I know it is possible to create custom web auth splash pages on the WLC 5508. Is it also possible to embedd a small document (less than 1MB) that users can download directly from the controller? I need this for providing the terms of use for the Guest WLAN.

Have WBR-2310 D-Link router. Internet modem and wireless router were working. While trying to connect new wireless printer, lost internet connect. Had to re-enter internet provider user id and password. Was told I needed to make sure that information was in my D-link router, so I typed 192.168.0.1 as internet address. I don't get a webpage to enter the userid and password.

We will be converting two 6500s to VSS. Each chassis has a Sup2T module, fwsm, 6908-10G blade, wism1 blades and two or three 6748-SFP blades. I was wondering how long the conversion process takes? If I remember correctly at the 2012 networkers lab it took maybe 10 minutes while using Sup720s. The instructor mentioned that with Sup2Ts it would convert a lot faster.

I have a year old E1200 router. I just updated the firmware today, made adjustments to the MTU range to suit cable service and selected a different channel (9) as the neighbors were mostly on channels 2 and 6.My question is really in regard to the speed results of the router. In the immediate room where the router is located I am getting 17.6 Mbs download speed/ 3.53 upload speeds but if I move to my living room - less than 20 feet away and a few walls - the upload speed drops sharply to 3.21 Mbs download/3.21Mbs uploas.I have read where the router placement can be key. My router is sitting on the desktop. If I elevate the router will it improve performance 20 feet away or should I invest in upgraded router like a E3200 or look into a plug in type repeater?

Would one of the 'Cisco RV016' work with a switch? I'm planning on running our work network using this device to load balance between 3 WAN connections and would like to keep the upstairs and downstairs computer users separated via a switch.Will the switch affect the load balancing or will the router still be able to detect each individual user and balance the load as seen necessary?

I can telnet to switch from checkpoint firewall access port and from switch directly. I can ping/traceroute successfully to the switch. Access-lists 14 & 15 are allowing the traffic I want. The router on the other side of the FW has 2 static routes and a default static route set up.
Here is some of the config from my switch:service tcp-keepalives-in
service tcp-keepalives-out
service timestamps debug datetime msec localtime show-timezone
service timestamps log datetime msec localtime show-timezone
service password-encryptionhostname xxxxx
enable secret xxxxxx
username xxxxxxxx password xxxxxxxip domain-name xx.xx.netaaa new-model
aaa authentication login default local enable line none[code].....
Not sure of checkpoint firewall config....I have run wireshark when trying to telnet and I get no syn-ack back from remote switch. Just 3 consecutive syn attempts.I have some switches I can connect to and they go right through the 3 way TCP handshake and I cannot find any differences in the configs between the successful connections and the unsuccessful connections.

I want to buy a WRVS4400N, but I need to know something before.
The router will serve as an access point for 10 wireless station, 6 of them will run over Terminal server, the router will also serve 20 computer for the internet, so I want to Link aggregate the four LAN port to my swtich, I know how to do it on my Dell Powerconnect, but I want to know if the WRVS4400N will support it, there will be a lot of traffic going through the router so linking the 4 port in LAG mode to my Powerconnect swicth will speed up the communication !
