Cisco Firewall :: 5510 Switch Does Not Have Default Gateway Configured
Nov 1, 2012
We have a 3560 switch behind a ASA 5510 at a site that we are trying to access via telnet over the internet, we find out the switch does not have a default gateway configured. So I configure the following rule on the 5510: [code] Try accessing the switch, and all is good. One of our change control steps is to identify any others are connected to the device via: [code] I see the connection and show users command return 172.16.30.15, as expected. How is it possible that address can connect to that switch.
We have two ASA5510s, each with outside interfaces to the same two ISPs (different IP addresses within the same subnet, of course). Both ASAs allow ICMP on all (inside and outside) interfaces. One ASA's default route is to ISP-1 and the other is to ISP-2. We can ping the default gateways for both ISPs from only one ASA. From the other ASA, we can only ping the default gateway for the default route but not the other. The pings originate from an inside client, first configured with the default gateway for ASA-1, then for ASA-2. Why does this happen, how do I troubleshoot something like this and how do I fix it?
how my switches are configured, a cisco 3750 and a cisco 4506.[code] i can ping the gateway from the 3750 however cannot get anything past that or enything to it.
We have an ASA 5510, with two internet connections. One inteded for VPN l2l and the other for general users inet access.
On asa 8.04, I configured the crypto map on inteface "VPNAccess" and a static route to the L2L remote peer through VPN internet access, the default rotue was pointing the general inet router.
We bought a new firewall with 8.4.1, and now asa only tries to initiate traffic if remote peer is on the default gateway.
It ignores more specific routes (i mean longer masks) and always tries to use default gateway, but only for VPN, if I make a trace route for that peers it uses correctly the routing table.
I'm really not clear about default-gateway on switch command, not the function but how its works.i have 1 multilayer switch (MLS 1) that have 2 vlan within it, vlan 2 and 100. on vlan 2 i assign ip address of 192.168.1.1 and on vlan 100 is 172.16.1.254. both vlans are up. then under that multilayer switch i added 2 more MLS (MLS 2 and MLS 3), and the links of MLS 2 and 3 to MLS 1 are trunking. and both MLS 2 and 3 have a same vlan with MLS 1. that i assign an ip address on vlan 2 in MLS 2 192.168.1.2 and i set default gateway 192.168.1.1, and i do the same to MLS 3 but the ip address of vlan 2 is 192.168.1.3i already setup the routing protocol on MLS 1 so that vlan 2 could contact vlan 100. but the fact it doesnt work at all, both MLS 2 and 3 cannot contact vlan 100 eventhough that are already have default-gateway setup, is there anything wrong with the configuration ??
I had setup a lan infrastructure with 5 3750 stack swithes. In these 3 of them are in one stack which is acting as access switch, 2 of them in another stack which is as core switch where all the SVI is configured. Now, when i tried to ping from our edge pc which is connected in access switch to default gaeway, which is configured in core switch, the ICMP is getting delayed . But when try to ping from the same edge pc to another user PC, it is getting less tahn 1 millisecond icmp replies.
why icmp is delaying to default gateway , but working with another edge to edge pcs without any delays?
It has ip helper configured that points to DHCP.From 4500 switch port - port x connects to 2960 port.Port x is configured as trunk between 4500 and 2960.
2960 config vlan 10 name data
All user ports are configured under vlan 10 and as access ports.Port x is trunk port connected frpm 2960 to 4500 switch allowing vlan 1 and 10 only.This switch has no default gateway configured.
We connected user PC on 2960 switchports and they were able to get the IP from DHCP server and were able to access the network? My question is how users on 2960 switch are able to access the network without ip default-gateway configured on 2960 switch?
I am testing rogue on wire using 5508 WLC and , I have a dedicated AP configured as rogue detector and configured the switch port where the Rogue detector is connected as trunk. I have plugged in an autonomous AP with open authentication to the same switch so that it can act as a rogue. On the WLC, I can see that Autonomous AP as rogue on Wire. But along with that I am seeing another AP as rogue on wire, even though i have plugged in only one Autonomous AP to the switch.
Currently a network consists of two subnets, one subnet is behind a ASA and the other behind a PIX, both connecting to the ISP's routers. If the PIX is retired, is it possible to create/consolidate the two networks protected by the ASA5510 with the default gateway being the ISP?
How can two private networks be protected by the ASA5510? One conceptual way is to create the VLANS on a layer 3 switch, on the "inside" interface of the ASA. In this senario what would the "inside" network's IP address? If the above is possible, how would natting occur?
Is there an efficient configuration to protect two networks protected by the 5510, other than creating a DMZ?
Is it possible to create two private networks with same level of security, 100 on a three network interface connections?
A customer got a new VoIP PBX, and now I have to forward port 443 on the ASA to the PBX for remote administration purposes. The LAN-interface of the PBX is in the same subnet as the ASA but has an external VoIP-router as default gateway and not our ASA. Is it even possible to forward the port to the PBX when there is no route of any sort to our ASA on it?
I've configured a VPN IPSEC on my ASA5510. It Assigned IP/NETMASK/Gateway via a DHCP Server on the LAN.The problem is that when a client is connected to the VPN , it takes the right IP and NETMASK. ( 192.168.1.109 / 255.255.255.0) but the Default Gateway is wrong ( 192.168.1.1). It should be the default Gateway of my LAN router ( 192.168.1.229).
I have a asa 5510 vpn client groups configured and connected to the internal network DHCP server stops giving network service dhcp and the network goes down.
I have an ASA-5510 in a location that loses connectivity to the wan gateway after anywhere from five to fifteen minutes. At first I thought that the unit might be defective, but I replaced it with an ASA-5505 with similar results. A reload of the ASA-5510 will restore connectivity for the next quarter hour.
Here's the version information on the 5510:

Switching out a 5510 as our primary firewall with a 5520. I've essentially copied the working config from the 5510, and put it on to the 5520, making small changes where necessary. Plug everything. I cannot get out to the internet.
Facts:
-All interfaces have no shut on them -No machine can ping out to the internet gateway -All machines can ping out to the inside interface of the firewall -It's not a problem with the internet because I can take a laptop, enter in our outside interface information, plug it into the internet gateway, and I can get out to the internet just fine.
I am having touble with a NAT concept. What I have is a 3rd party software VPN product that basically tunnels encapsulated traffic to/from a server sitting inside the network. Right now this traffic utiluizes a physical interface on the ASA5510, but I need the interface for another project.
I am having an ASA 5510 and have configured Clientless SSL VPN in it. Now I need to allow my SSL VPN user to access on a particular application(like mspaint.exe for example).When the user login to the SSL VPN, he should see only the particular aplication or must be able to access on the particular application.
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.
Can ASA 5510 be configured as bridge mode and still send Netflow info to a collector?We have a PIX connect internal network to internet. Because PIX does not support NetFlow, as a temporary solution, we were thinking of putting an ASA 5510 between the PIX and internet gateway, and configure it as a bridge so that there will be no routing issues, and the ASA can still send Netflow info to a collector.

i joined because i keep on having the same problem. i read around the forum a bit before joining and i saw that mcafee was causing the problem for a lot of people. i dont have mcafee so that cant be it several crashes per day. like, literally close to 100 of them.
Periodically, I drop internet everywhere around my college's campus. I'm literally four feet from a router, but it doesn't seem to matter. I'll disconnect, run troubleshooter, and I'll get the error message saying that the default gateway is not available. My college is designed for Macs, but I'm running Windows 7. My Mac colleagues do not experience problems. The computer works at home and at nearly every other wireless network I've brought it in range of. Specifically, either IBM or Dell.

I recently got a new laptop and ever since, the internet goes in and out. Most of the time it is not out long enough to display the no connectivity icon or stop music from streaming but it is noticeable. When I run the troubleshooter it says that the default gateway is unavailable. I tried manually setting the connection information but the same thing keeps happening except the troubleshooter then says that DHCP is not enabled. I've disabled every firewall I can find and updated all the drivers available. Here is my info:[CODE]
I am trying to get rid of 2 old 2651xm's and 2 2950's from my CCNA days and want to get into the ASA realm. Can I be able to use the ASA, not only as a security appliance / firewall, but also be able to write the access lists, etc, to be able to use this as my router to push packets to and from my internal LAN to the outside world? I guess I should have stated as this being the front end device to my network, just after my DSL Cable modem, that is..and being the only device. I am trying to have this as my main router /firewall solution and then I have an old Linksys router I will pipe off one of the L2 ports to have an AP for my wireless devices? Is this a real solution an ASA can provide?
i'm having problem to ping succesfully default gateway on Router1 from Router2. Basically i can: - ping from R1 the serial interface on R2 and default gateway on R2 - telnet from R1 to R2 - ping from R2 to serial link on R1, BUT I CANNOT ping default gateway from R2 to R1 Below is the photo showing topology and running configuration on both routers
We have a network consisting of a central site and a few remote offices. The sites are all connected via MPLS and also have VPNs over ADSL / internet connections as a backup. The remote offices have Cisco 837 routers for the ADSL connections which we can manage but the MPLS routers are managed by the service provider providing the MPLS connections. At the central site we have a Cisco 891 for the the MPLS connection (which we manage) and a Cisco ASA5505 for the backup VPNs.
In order to implement failover from MPLS to VPN in the event of any MPLS line going down I have tried to use ip sla monitors and tracked objects on the 891 as per Cisco's documentation. The problem that I am finding is that I can't set the number of ICMP echo failures required before the tracked route is dropped. Whenever the ip sla monitor fails to get a response the tracked route is dropped immediately. This is too sensitive as packets are occasionally dropped which results in the routes bouncing back and forth between MPLS and VPN too frequently (disconnecting users in the process).
I have tried different threshold types and values, tried configuring ip sla monitor reaction-triggers (although I don't understand what little documentation that I can find on this) and have even looked at event manager. I have been working on this for a few weeks now and am getting nowhere.
The Cisco ASA5505's implementation of ip sla monitor is much better in that it is possible to specify the number of packets but unfortunately we can't use the ASA as the default gateway for the LAN as the asymmetrical routing that occurs does not work with the firewall function of the ASA.
Any issue with ip sla monitor on IOS and managed to get it working?
When I plug my laptop up to our modem, all i get is local access. IPconfig gives me to default gateway or dns suffix. Naturally there is no wireless. My roomates laptop runs fine wired or not and we have the same set up.Not sure what to do.
I am having issues playing certain games on my ps3. So I've been searching for solutions and I came across a video that wanted me to go to run/cmd/ipconfig. I have little knowledge of computers but I'm not sure that what my ipconfig is showing is supposed to be there. At first I googled and learned about ipv6 addresses because i found that weird but i think that checks out fine. I then googled about the weird numbers and letters in my default gateway and came up empty. Is there a reason thats there?
I have Squid proxy installed on a ubuntu box here. Currently all my PC's use my ADSL modem as their default gateway but what i wanted to do was see if it was possible to use the ubuntu box as the default gateway, and have it route through Squid to my ADSL modem.
I am trying to change the password on my D-Link router. So i typed ipconfig into cmd and the default gateway i get is 169.234.95.I have tried what used to work at home such as 192.168.0.1 and all of those.
I have a VM server, whose IP is in customer VLAN600 ( 172.60.60.10/24 ) and Peer end is switch then Firewall.Switch is configured with same VLAN600 and learning mac-address of Server on VLAN 600, Firewall is also having VLAN600 and IP is 172.60.60.1/24.Server is not able to Ping/reach Firewall and vice versa.
