Cisco WAN :: C2900 - Assigning Multiple ADSL To GE Ports
Jan 19, 2012
I have 1 x C2900 router with 3 x ADSL WIC and UC500. I setup 3 x ADSL to access internet and UC500 is connected with 3 telephone lines (plugged into FXO ports). I have 2 x GE on my 2900. 1st GE is connected to switch and 2nd GE is connected to UC500.
I want to setup that traffic from UC500 (SIP) is going through 1 dedicated ADSL line and data (from computers & servers) is going through remaining 2 interfaces only. How I can set it up.
I would also like to know how I can load balance internet connection going through 2 dedicated data ADSL lines.

We are looking to possibly purchase 2 RV042G routers. The main goal is to tie 2 sites together (via the internet) utilizing the site-to-site VPN feature.
Here is where it gets a little tricky. Since this device has 2 WAN ports, is it possible to assign a seperate IP address for each from our ISP? Then, what we would like to do is assign a couple LAN ports to have the traffic flow through WAN1 and the other LAN ports to flow through WAN2. The LAN addressing can be on the same subnet or seperate.

Is it possible to assign a single ssid to multiple interface groups by assigning the ssid to multiple AP groups?
I have buildings geographically dispersed that are configured with multiple vlans in interface groups so that I can maintain an addressing scheme of dhcp assigned addresses per building. Each building is also further grouped as AP groups. I'd like to know if by assigning the same wlan ssid to each of the AP groups, will I maintain addressing integrity for each building? I'm thinking it will work.
Do the buildings have to be outside AP range of each other to avoid problems?
5508 controller
7.2.110.0 code
6 buildings
6 interface groups
1 ssid

I am setting up a 1921 with two ethernet WAN ports going to two seperate ADSL ISP's (via bridged modems) and one connecting to the internal LAN. There is a single e-mail / web server behind the router.
I have been reading the following which is exactly what we want to do, but I have questions. Maybe failover would be better because Load Balancing seems a little too quirky without BGP. url...
How do we define public static IP's, the example seems to show DHCP?In order to detect if a line is down, it has to ping an IP address that is specific to the connection - correct? So could I use the gateway for the ISP? The issue I have with this is the gateway might be up, but the Internet down. Next, we need to make sure that when someone visits one of our public IP addresses, the return data is sent through the connection requested. What we don't want is a situation where incoming connections are not working.From experience, load-balancing causes certain websites and SaaS applications to break because requests are coming from two different ISP's. Is this the case with OER? Finally, any links, config or something to advise how a fail over only configuration would work given we have internal servers (PAT/NAT inbound would need to translate properly with the failover IP)? Basically if ISP 1 goes down, I.E. router cannot ping 8.8.4.4 then it switches to ISP 2, until ISP 1 comes back online and switches back? This would need to change the NAT rules for inbound as described.

I need to create multiple ip-sec vpn tunnels on A Cisco 837 ADSL Router. I am able to create one tunnel but the second connection is asking for the outside interface which is atm and already taken by the first tunnel. How can i create more tunnels?
Secondly, after creating the first tunnel i am able to access the remote lan network but when i tried tracert "remote lan ip of a pc" from my pc i got "request timed out" after passing my 837 but succeeded to reach the target. Does tracert needs something to be opened in the router?

I have Cisco 871 router with 12.3. OS version.
1. I'm interested if it's possible to block certain contetn only at certain time ? e.g. We would like to block facebook from 7:00 to 10:00 and from 11:00 to 15:00. I was going through cisco manuals but can't find the right answer to this.
2. Cisco 871 has 4 LAN interfaces and one WAN interface. Currently WAN interface is connected to adsl modem in bridge mode and LAN 0 interface is connected to switch.
I'm interested if I could use remaining 3 LAN interfaces for adsl connections same as I'm using WAN interface. Then I would create vlans that would use LAN interface 0. Each of those VLAN's would use different adsl connection.I would assign different IP to each VLAN's so users would be able to change their gateway and use different ADSL connection.

At home I have a D Link DSL-2640R wireless adsl router/modem in my downstairs office.I would like to use the cable which goes to upstairs of the house to link to some sort of extra router or switch in order to provide more network ports upstairs.

My internet is running through a D-Link DIR-655 router at home it's giving me some problems at the moment.Me and my roomie both play World of Warcraft and we both have to have the ports open for updates, and it won't let me.It will only let me open the ports for 1 IP, if i try to open it for more it 'conflicts', it's only passing through the port in the router, it's not dedicated to one IP.

We've read everything about inspecting SIP packets and allowing them to pass through on port 5060, the default SIP port. However, our setup requires the ASA 5505 to allow SIP on ports 5060, 5160 and 5260.
Is this possible with the ASA 5505? If it's not, it would be a blocking issue for us to move forward with ASA appliances. We are currently investigating in a lab environment and really having difficulties configuring it to facilitate full SIP functionality.

Currently migrating from a CSS to a new ACE for all our inbound ssl connections.
On the CSS, I could define multiple backend services, different tcp ports and 1 IP.
ex.
service TEST_HTTP22
protocol tcp
[code]....
But now I have to define each backend web server as an RSERVER and it doesnt allow me to configure 2 rservers with same IP.

I have a wlc2112-k9. I have succesfully setup a WLAN with 802.1x authentication and dynamic VLAN assignment. The issue I have (and maybe it isn't an issue and just the way the controller works) is that if the vlan interfaces I have defined are connected to different ports from which the default interface for the WLAN it doesn't work.So for instance, I create my WLAN and set the interface to the management interface (which is connected to port 1). I then define all my other vlan interfaces that could be returned by my radius server.[code]
Port 1 is configured on the switch on vlan 21. If the radius server returns a VLAN ID of 102, 104 or 106 my client successfully connects to the WLAN but it gets put on VLAN 21. However if I move the vlan interfaces above over to port 1 the client correctly gets put on the correct VLAN.All ports on the switch are configured as trunk with the native vlan set to the corresponding value that is set on the WLC.
Is this just the way the controller functions? That it can't assign a client to a different interface that is connected to a different port from the default one setup when the WLAN is created? I would have just though that if the radius server returned VLAN 102 that it would find that interface and connect the user session via that interface regardless of the port it is configured on.

I have a client with a cisco 1841 router with a static public ip. He has 3 dvr's he wanted to acces from the internet and we opened the ports for the dvr's ip's. The issue were having is that only the first ip that we opened shows the port opened and works ok, the other 2 ip with their ports show closed.

We are migrating from a nother brand to an ASA Cluster running 8.4.5
We have a web-server on an inside interface listening on a non standard port - 20111. We have created a static NAT translating the public ip to the private, so If I do http://public-ip:20111 it works. (we are using a seperate public IP for this service only).
Now I need to create a NAT rule that will forward requests on BOTH port 80 and 443 to the same private ip and the same port number (20111)
The Private address is 10.99.250.20 and the "public" (I've replaced it in this example) is 172.16.16.16 I have managed to create a NAT that will translate 443 to 20111:
object network 10.99.250.20 nat (Private-DMZ,Outside) static 172.16.16.16 service tcp 20111 https
But if I try to add another rule like: nat (Private-DMZ,Outside) static 172.16.16.16 service tcp 20111 http It will simply replace the first one.
Is it possible to redirect both 80 and 443 from outside to the same port number and same IP on the inside?

I was wondering why can't we no longer use the multiple ports within an extented ACL like I use to do it in a CAT3750E.I have IOS-XE Software, Catalyst 4500 L3 Switch Software (cat4500e-UNIVERSALK9-M), Version 03.02.00.SG.I wanted to create an ACL like so [code] But when I do, it tells me that I cannot do it.... I can only add 1 tcp port to my ACL line. I tried to search the "object-group" concept also but it's not implemented in this IOS.Can this be done in IOS-XE ?I'm migrating my enviroment from a CAT3750E stack to a C4510-E.

I've run a across a strange issue that I've not encountered before and after the things I've tried am beginning to think it's a limitation of the router itself. What I have are 3 Cisco 1941 routers that are all endpoints for a customer's MPLS network. STL is the headquarters and both remote offices have a link back this router. Each of the remote locations only have 1 serial interface. It is a flat network with few routes and a small shoretel voip system running across it. Each router is running C1900 Software (C1900-UNIVERSALK9-M), Version 15.0(1)M5, RELEASE SOFTWARE (fc2).
QoS is configured as follows on each router:
class-map match-any AutoQoS-VoIP-Remark
match ip dscp ef
match ip dscp cs3
match ip dscp af31
class-map match-any AutoQoS-VoIP-Control-UnTrust
match access-group name AutoQoS-VoIP-Control
class-map match-any AutoQoS-VoIP-RTP-UnTrust
[code]....
If I try to apply the policy map to serial0/0/0, I get the following error:
% policy map utoQos-Policy-Untrust not configured
I've tried to create a different policy map with the same settings and get the same error. We thought that when it was first set up, each interface belonged to the same network, so we separated things out (hence the .252 mask). I'm not sure what else to try and I'm hoping its something painfully simple that I'm missing.

I've got a recurring them developing across several deployments of Catalyst 3750X series switches, I'm seeing large amount of output drops across multiple ports but there are is no QoS deployed on any of these switches. (standard FiFO). As it happens the ports in question are a member of EtherChannel groups which are connected to ESX Hosts.I've also seen this behaviour also unexplained on another 3750X at a different site, however it's a single port and connects to an Upstream firewall.However in both cases neither switch has any QoS or non-standard configuration, literally a couple of VLAN's and some EtherChannel groups.Here's some output from the case involving the ESX servers.

I'm stuck at asa 5505 nat, port forwarding configuration Here is what i need:
host1: 192.168.1.1 service tcp/100 >>>>> public ip 1.1.1.1 service tcp/100
host2: 192.168.1.2 service tcp/200 >>>>> public ip 1.1.1.1 service tcp/200
host3: 192.168.1.3 service tcp/300 >>>>> public ip 1.1.1.1 service tcp/300
So people from remote just need to use 1.1.1.1 public ip to access all the ports on three different inside server.I can do this on my old ASA 5505 with 8.0(4). Looks like there're lots of change from 8.0 to 8.4.

I have 2921 router and I have 3 very basic switches that I need to connect to the router. The switches have very basic default configurations and there is no way to edit them, so I only have one VLAN and one default gateway. I can't assign the same IP address to each LAN port. I'm not sure how to make this setup work.

I have an rv180 and I'm trying to setup a custom service that contains both multiple disjoint ports (some UDP some TCP), as well as a TCP port range. This has lead me to a couple of questions.1) Is it even possible to have a single custom service with disjoint ports? Is it just going to be necessary to define multiple partial services for this?2) Is it possible to forward a range of ports? It's clear how to define a service with a port range, but the port forwarding table interface only allows me to select one LAN-side port for any service. Is there a secret notation that I need to do here that will just forward to the same LAN-side port as the WAN-side port---effectively one-to-one NAT forwarding, but just for the selected service?

We have a vpn L2L with an ASA and C2900 and always stopping to ping each other but the vpn still UP and can each the others devices behind the peers.
Everytime we have to issue on router "clear cry isa peer" or on asa "clear ipsec peer" to start to ping each other but after seconds it's stopping to ping again.Is there something to fix it permanently? We did some debug crypto on asa but no information was logged.

Previously posted as C2900 - inward NAT partial success...
Running C2900-UNIVERSALK8-M, Version 15.0(1)M3 RELEASE SOFTWARE (fc2)
I have several sets of inward NAT defined (51001-51007, 52001-52007. 53001-53007),all to various internal addresses. When I attempted to add another set, the new onesdo not work and get a "timeout" error.
When I tried port 51008, it gets a timeout. When I changed 51008 to 51010, the 51010 now gets a timeout, and 51008 now gets "connection refused" (which I expect).The original sets all work, the new ones (added at the end of the lists) do not.When I am on any of the internal machines, the target (192.168.1.21) works fine.When I am "in the router", I can connect via the ssh command, so I know that therouter can talk to 192.168.1.21 on port 22 as expected.

We are facing a strange issue with GRE tunnel. We are using this tunnel from a branch office to Hub office. All other tunnels terminated on Hub router are working fine. Issue with this tunnel is that whenever WAN connection goes down Line protocol on tunnel interface some times comes up and sometimes not (therefore we have to reset the tunnel interface and it comes up). IOS used on this router : c2900-universalk9-mz.SPA.152-1.T2

I have a mixed WAN environment with both eBGP and EIGRP routes. The BGP routes should always take precedence, when they exist. If no BGP routes exist I want the router to fail over to using the EIGRP routes. So far, this works fine.
The problem is, when the BGP route again becomes available (and the associated entry appears in the "sh ip bgp ... received-routes" output) the router is NOT relinquishing the EIGRP route. It remains in effect, showing as a "D" route int the route table even though there is a better ("B") route available. If I bounce EIGRP or the interface associated with it, the EIGRP route disappears and the BGP route reasserts itself, and everything will run correctly until the next time the BGP route disappears due to maintenance, line failure, etc.
My router is (C2900-UNIVERSALK9-M), Version 15.3(1)T
Here's the associated config
interface Tunnel101
description VPN backup WAN interface
bandwidth 7168

Does Nexus 7K support Multiple VDCs sharing ports on a single line card. One of our cisco parnter engineers stated that cisco doenst recommend using same line card for multiple VDCs.The second VDC (Non-Default VDC) will be used four our Outside, and DMZ Segment, and to phyiscally segregate our Firewall from our Internal/Inside Core Switch without using a physical DMZ Switch.I know Cisco used the Nexus in this way in their PCI DSS 2.0 Compliance Document.
