Cisco Routers :: Configure SR520 To Route Internet VLAN To Firewall
Jan 20, 2012
My operations manager says "Could you go on-site and configure a new clients new internet connection?" I make the arrangements and go on-site. As I'm working with the providers tech he says "Do you have a sub-interface confgured for a dot1q VLAN id of 1057?", I say "What?". Anyway my firewall is not capable of dot1q VLAN, so he says "Do you have a Cisco router that can provide the trunking?", I say "Yes, I tink so but not with me". The question is can I use an SR520 between my firewall and the provider demarc to route the VLAN he is talking about? My initial discovery says yes but I am not quite sure of the details on how to achieve this on the SR520.

I'm trying to configure a zone-based firewall on an SR520 and am confused about the 'not' criterion. The 'zone-design-guide' says (my stress): Class- maps define the traffic that the firewall selects for policy application. Layer 4 class-maps sort the traffic based on these criteria listed here. These criteria are specified using the match.where my intention is to let only LAN hosts with IPs in the range 192.168.1.1 to 192.168.1.7 out through the firewall. There may be an easier way of doing this which I'd be pleased to hear about. But, even if there is, I'd also be interested to know what I'm doing wrong in the above.

Just picked up a ISA550 and have been playing around with it a bit but seem to be having some trouble. I have two LAN subnets in my small business with approx 10 hosts per subnet. I'd like to use the ISA550 to route between them (and to the internet) but can't seem to figure out how. Is it just as simple as creating two VLANS? Can the ISA550 route VLAN traffic?With my old RV042G, I had the option to setup multiple subnets inside the setup menu but I don't see any such area with the 550.

I´m trying to configure SR520 Cisco router as PPPoE server. The point is, when configuration is done and PPPoE client is directly connected to the interface, SR520 doesn´t respond to incoming PADI. PADI is not shown in PPPoE debugs (debug pppoe events, packets and errors).On the other hand, I get the PADI capturing packets with wireshark (so PADI is being sent) and the same configuration on other router works fine.

I'd like to configure a VPN with two SR520. the first router is a SR520-FE-K9 and it's at office, the second router is a SR520-ADSL-K9 and it's at home.
Each router have a static IP and individually works well. I tried to configure, by CCA, the office router as a server and the home router as a client: at home I can't see the office network and I can't navigate.
Need step by step, using CCA to configure a secure VPN.

How to configure ASA not to drop packets with ip option 7 (record route)? According to the docs, ip inspect ip option will drop all ip option packets except 0,1,and 20 (EOOL, NOP, or RTRALT):
"If an IP header contains additional options other than EOOL, NOP, or RTRALT, regardless of whether the ASA is configured to allow these options, the ASA will drop the packet. "
Also, policy-map type inspect ip-options treats only these 3.

How do I submit an RFE (Request For Enhancement) to the Cisco SBR team to encourage them to implement the missing support for VLAN to VLAN firewall rules that was available in the RVS4000 (See [URL]) and that was supposedly added to a beta release of the RV220W firmware (See [URL])?

Im trying to configure a SR520 with the CCA, but every time I try and apply the changes to the router i get the following error.
"java.lang.nullPointerException"
Using CCA 3.0(1) and Java Version 1.6.0_16 from Sun Microsystems Inc?I assume this is an issue with Java, as like with the SDM you had to use an Old Vertion.

how to configure a backup route to the internet. My client has 2 ISP and basically they want to use 1 ISP and in case the ISP fails, use the other one as backup route to the internet.
The problem I’m facing is that each ISP is plugged to a dedicated ASA 5510, so 1 ISP in one firewall and 1 in the other. Both ASA are plugged to an internal network in a dedicated VLAN with a L3 switch and that L3 switch manages the internal network.
My question is, how can I tell my switch to use ASA1 to go out to the internet and in case the ASA 1 OR THE LINK TO INTERNET used by ASA 1 fails, use ASA 2? It would be great if I can send traffic to the internet thru both connections at the same time. Also, I know the ASA has High Availability configuration, but that applies only if both licenses in the devices are the same and I have a mismatch with the SVPN license, and also I don't know if with my current topology I can use the High Availability model, so I think I can’t use that option and the solution must be applied in the L3 switch, but I don’t know how to tell it to use ASA1 and if failure of the device or the outside interface plugged to ISP 1, then use ASA2. Besides, I would like to know how to optimize this config to do the switch between internet connections seamless to the users if possible (there are VoIP calls on this floor, so I don't want to drop the calls).

I've been given the task to clean-up our network config, and have walked into a disaster zone.We have a 4510R on site with everyone using the default VLAN, VLAN 1.I have created 4 new VLANS, VLAN100, VLAN150, VLAN200, VLAN250 I have assigned interface addresses to each VLAN and configured Inter VLAN routing.I can route to and from each new vlan with no problem, i.e VLAN250>VLAN100 VlAN100>VLAN200 etc but I can't route to VLAN 1(Default VLAN) from any of them, I can ping the interface on VLAN 1 from any VLAN , but any hosts are unreachable. On the flip side , from VLAN 1 I can route to all of the VLANS.

I have a PIX-515E that I'm trying to configure for what I thought would be a simple task. I've been playing with VMWare ESXi on a Dell PowerEdge 1850 in a lab environment. The server's IPMI is bound to one of its two physical interfaces, which I've connected to Ethernet 1 on the firewall. The interface has the following configuration:
PIX Version 7.2(4)!interface Ethernet1 nameif FrontEnd security-level 40 no ip address!interface Ethernet1.2 vlan 2 nameif IPMI security-level 90 ip address 172.16.0.161 255.255.255.224
The server's baseboard manager has been configured to tag its traffic on VLAN 2, priority left at 0 (default), and its IP address appears in the firewall's ARP cache; however, here's what I get for a ping response: Sending 5, 100-byte ICMP Echos to 172.16.0.164, timeout is 2 seconds:?????Success rate is 0 percent (0/5)

We have a wifi network for guests, that we route to internet through an old PIX515 Firewall. We recently tuned the timers to lower values in order to "save" on resources and publix address usage.
The timers we use are:
-timeout xlate 0:30:00
-timeout conn 0:30:00 half-closed 0:05:00 udp 0:02:00 icmp 0:00:02
Through verifying the new timers, we noticed at some xlate connections (TCP PAT) that are idle for ever!!In the connection table, I cannot find an idle connection for longer than 1h....

i have a demroom set up which includes a sr520 as the edge router connecting to the ISP and i have a uc 560 connected to that which is working fine i also have a new business edition 3000 and a 800 series router which im looking to connect to the sr 520 for access to the ISP as the 800 series doesn't have a ADSL line on it .i have given the 800 series routers wan interface a static address of 192.168.75.14 wich is from the address range in the sr520s default vlan and excluded the address from the DHCP pool. now from the ccp express on the 800 s i can ping the wan port of the 800 s and the default vlan/gateway of the sr520 and the wan ip of the sr520 but no further also once i try pinging it from the cmd on windows i cant ping any further that the wan interface on the 800 s .

I'd like just notify the missing "no ip name-server" command in sr520 series router. However is possible to enter the command "ip name-server" the only way to delete it is to copy a modified config from tftp or other source to the startup config. This behavior is normal?

I recently added a business cable modem to relieve some of the congestion I was getting on my T1 for our MPLS network. There was an ASA 5510 collecting dust in a closet here and I thought it would be the perfect device for firewalling the traffic coming in from the Cable modem, and handling the routing of our internal MPLS traffic as well. Internet setup was cake. The test laptop I have using the ASA as it's gateway has great internet service but it cannot ping across either of our MPLS networks. I have one MPLS with AT&T and one MPLS with EarthLink. My hope was to use the cable modem as the Default route for all unspecified internet traffic and route our internal MPLS traffic to the cisco 2800 routers that are currently in place for the MPLS. I can ping across the MPLS when I telnet to the ASA, but I cannot ping across the MPLS from the client that is connected to the ASA.
Here's the topology I'm working with

I'm trying to combine dynamic and static NAT on a SR520. My dynamic NAT is specified with:ip nat inside source list 1 interface Dialer0 overload access-list 1 permit 192.168.0.0 0.0.7.255 In addition to this I want to perform static NAT for a couple of selected internal hosts. I can do this:ip nat inside source static 192.168.1.5 10.85.10.2 which works fine but means that the source address 192.168.1.5 is translated to 10.85.10.2 for all destination IPs. What I want is for the above static translation only to occur for a particular destination subnet.To accomplish this I have tried:
ip nat inside source static 192.168.1.5 10.85.10.2 route-map toOtherSite
route-map toOtherSite permit 10
match ip address 150
access-list 150 permit ip 192.168.1.0 0.0.0.255 192.168.10.0 0.0.0.255
But this does not appear to work. Instead it seems to render the host 192.168.1.5 unable to progress through the NAT, whether the destination subnet is 192.168.10.0/24 or not, and I can't work out what I'm doing wrong.

I just received a new SR520-FE router and am having a hard time getting it configured right. AS of now it is in my lab in a simulated "customer environment". I can ping what's behind it, what's in front of it. But I can't get outside access. I know it's probably something small so I am hoping another pair of eyes might be able to see what I don't. Here is the running-config. It's the factory setup minimally adjusted.

We've (an independent school) just bought an SR520 with a view to replacing one of our Draytek 2820s. We need to set up some site-to-site VPN with NAT and the Drayteks won't do it.
I've been trying to configure the SR520 in just the most basic fashion using CCA (3.1) and the CLI but with no success. I can't get a PPP connection with our ISP.
I've tried following the instructions in the software config pdf and also tried replicating the various 'running configs' reported in other posts in this forum to allow connection to a UK ISP, with no success. I don't know how many times I've reset the poor thing to factory defaults.
I have to say that I'm dismayed at how flaky the CCA appears to be. Many of the things I've tried with it simply don't work and often end up in it hanging. Close to useless in my view.
So instead I've tried to use the CLI which seems a lot more solid but is somewhat impenetrable and there's precious little by way of supporting explanation.

I've enabled antispoof on all interfaces on asa 5510.If you start a traceroute to a network on the default route, everything works, since replies comes to an interface with route 0.0.0.0/0 defined.If you start a tracer route to a network that is NOT on the default route (let's assume coporate MPLS), you only get response from first carrier router, the other are discarded because of anti spoof violation.
I have ICMP inspection and icmp-error inspection enabled.

I got myself lately Cisco SR520 router with some basic firewall functions built in. This is going to be used for my home broadband, so no need to be really super secure, as it would be for some business. I managed to configure it, however there are few things on the firewall side, which I don't understand.
This router had some default configuration in it's flash, when I bought it. There are class maps.... how it works or how to add/edit rules. Also, do I need to use class maps, or can they be replaced by ACL's to certain extend? How to add/edit class maps rules to allow certain port (eg. 3333). Pease see below part of the default config:
class-map type inspect match-any SDM-Voice-permit
match protocol sip
class-map type inspect match-any sdm-cls-icmp-access
match protocol icmp
match protocol tcp
