I have a 5510 that has 2 site to site vpn's that aren't working. Phase 1 and 2 are up, but no data packets are being sent. This just started randomly 2 days ago after working for weeks.
View 6 RepliesI am seeing a problem with our Cisco 300 switches. We use these switches as access switches, with a stacked 3750-G at the core, two 2960-S at the distribution layer, and about 10 300 Series switches at the access layer (10 port and 28 ports, all PoE).
We use Voice VLAN (VLAN 14) for our Mitel phones – there is a DHCP server on the Mitel system. Phones come up, get tagged VLAN 14 (LLDP), Traffic flows (including Broadcast for DHCP etc…). The system works, and has worked for months.
One day, suddenly, I find that all the Mitel phones on a particular access switch are not working. I look on the Mitel system and the lease on DHCP has expired, and the phone is stuck on renewing its DHCP IP address. I run port mirroring on the switch for VLAN 14 to see what is happening. The phones are stuck on DHCP discover, and I see the DHCP Discover broadcast packets on the switch but nothing else, no DHCP offer packets – hence the phone stuck at boot cycle.
I then do a port mirror from another access switch (that is currently working) – I can see the broadcast packets from the Mitel phones on the broken switch, but on this switch I can also see the DHCP offer packets from the Mitel system. I run two port mirrors simultaneous from the two switches (one working, one not) and I can see that the DHCP offer packets are not coming through to the broken switch. Panic ensues – I look at the distribution layer and there is no problem what so ever.
For some strange reason, the Cisco 300 28 port has stopped passing DHCP broadcast packets on a particular VLAN, even though they are being sent. I power cycle the switch – and hey presto, DHCP offer packets are coming through, and the phones get an IP address and boot properly.
Forward a couple of weeks later, and to today. I have another phone that is showing the same symptoms, luckily it is the only phone on this particular Cisco 300 28 port. The same issue is occurring as described above. I gather as much diagnostic information I can then reboot the switch – but still no joy. I then remember that this switch is not directly attached to the distribution layer and instead gets trunked to another Cisco 300 28 port. I give that a reboot and 5 minutes later, DHCP broadcast offers are passing and the phone boots.
I am listing this problem as not just a ‘one off’ now, and is recurring. It has happened to two of my 300 28 port switches.
All Switches running 1.1.2.0. No link to up time – first instance of the problem, switch was up for 14 days – second instance (another switch) uptime of 39 days LLDP is working fine on the switches, as is Voice-VLAN (Port is tagged and broadcasts out DHCP Discover which is seen by other devices throughout network) Nothing in the log file on the access switch Nothing on the Dist/Core regarding STP – Spanning tree set up is fine throughout.
I am currently using a 1841 router with AdvSec 12.4(24)T4 IOS on it. I used to have a working SSL tunnel configuration working, but for some reason it had disappeared and I am rebuilding the configuration. Unfortunately, I have been able to configure the router to perform the SSL tunnel, but I am not able to pass any data through the VPN. I am only able to ping the inside interface of the router and this is it. If I try to extended PING from the router to the remote PC I am able to get replies. Trying to PING anything on the remote network does not provide any responses back. I am thinking there is some sort of routing not happening here or I am missing some sort of configuration to allow the VPN to pass data through correctly. [code]
View 2 Replies View RelatedJust setup two WAP200E's, the bridge is "Connected" as I look Status > System Performance in both WAP's. However, I cannot get to the LAN from one network to the next. Cannot even ping the WAP's from either side.
I already have two WAP200E's on this network, that have been working well for month (164 day uptime), and they are configured with a wireless bridge between them, both networks on the same LAN (same 192.168.2.x network on either side). The bridge names are different, different from the main WiFi in the building, too (if it makes a difference), and the static IPs the WAPs have don't appear to have any conflicts on the network.
This is actually three buildings, one is the main one with a Cisco SR520 for a router, and a Cisco SF 200-24P switch. So two WAP200E's go into this switch now, and I see them both fine when going into the management interface. Then each of the other buildings has one WAP200E, and a small Netgear 8 port PoE gigabit switch at each building to power the WAP.
The Netgear switches aren't managed, and I've made sure any features like STP, VLANs, etc. are turned off. And the Cisco SF 200 switch is set at auto and all the defaults mostly, particularly for the ports. I tried doing a SmartPort for this latest WAP200E and that didn't change anything, tried disabling STP for it too, and no change. The PoE port for the working WAP200E is identical in config to the PoE port for the new WAP200E, and both show forwarding, all VLANs admitted (none are enabled, no VLAN tagging, etc.).
So now I am wondering if I can have two WAP200E's into one switch? Or two bridges on the same LAN subnet? Or is there something else I am missing or should configure?
I'm struggling with a configuration issue on the Cisco SG200-08P. We are using the Cisco SG200-08P on a mobile cart that will go from class room to class room that will have computer and cisco Voip phone plugged into it. The issue is that each of our closets are in differnt VLANS ( 1 voice and 1 data....lets say data vlan 20 and voice vlan 2025 for conversation) and that we route to each closet.It would be great if I could just create a generic data and voice vlan to dynamically pick up what the upstream switch has however, it seems that I've been unsuccessful in doing so. I can pass the data Vlan no probablem. The upstream switch port is set to access port and a switch port access voice vlan (these are 3750x switches) If the above is not possible I guess I will take what I can get. Should I just create data vlan 20 and voice vlan2025 on the Cisco SG200-08P and make a trunk port on the Cisco SG200-08P and a trunk on the 3750x? Is there an option on the Cisco SG200-08P to tag voice traffic?I'm also concerned with VTP and I did not see an area in the Cisco SG200-08P to set that as a client and transparent mode.

I have 2 ASA 5510 firewalls at 2 different sites. Both running on version 8.0.4. Users are using an Instant Messaging type of application provided by a local telco here which is able to send and receive SMS using SIP (from the packet capture that I've done).
When users use the IM in site A, they are able to send and receive text messages via the IM from behind the firewall. However, when the users are in site B, users are able to send out text messages but not able to receive them.
I noticed that when I remove "inspect sip" from site-B's global policy map, users from site-B can successfully receive text messages. I have confirmed that it is the firewall that drops the packets as I have captured the inside and outside interfaces of site-B's ASA and I can see the incoming sip "request: MESSAGE" packet on the outside interface but I do not see the packet exiting the inside interface.
I have cross check both firewall configurations, and I do not see anything suspicious commands relating to sip that might cause this issue. Is there any command to troubleshoot why the sip inspection is dropping the sip packets on site-B?
My SIP provider is not convinced that my ASA and Edge Router is not altering the SIP packets. On the ASA I've removed the inspect SIP, and H323, what else needs to be done to make the firewall not mess with the SIP Traffic.
Packets are flowing in/out.

I have a question regarding firewall configurations. Is it possible to have two interfaces ( for two internet service providers) one for voice and one for data. Can I have two Outside Interfaces that one will apply to a pppoe client group and the other will apply to a static IP? Is this possible and if so What would be the steps on applying this connection? Also to note I have a point to point connection already established for the pppoe. I also have another point to point connection for data, but however I do not know how to apply this to the firewall.

View 8 Replies View Related I am not a ASA expert but I have configured them few times. I have a vision of a task I have to complete but not sure if it is practical or how to go about doing it.
We two locations, Location A and Location B. Both locations have a 100MB internet conection. Location A has a ASA 5510. Location B has a 5505. Users at both locations access the internet via their respective ASA. Location A is the headquarters and Location B is a disaster recovery site. We want to setup a tunnel between both ASAs. This tunnel will be used to replicate data between the two locations for DR purposes. We need the users to still use the same pipe to get to the internet but want to allocate 10MB for internet use and the remaining 90MB for the DR tunnel.
We will be moving to a new data center in the very near future and with them our WAN IP addresses will be changing. Any best course of action for changing the IP addresses throughout the firewall configuration? Would it be possible/suggested to export the running-config, make the neccessary changes, then import the config? I am familiar with the ASA 5510 only so far as changes are required. It is not something I work with on a regular basis.

View 8 Replies View RelatedI have a vendor that currently uses a Cisco 871 as a VPN router in our company network, they use it connect to provide services to one of the servers in our LAN for our customers. Recently, we are going to be setting up a 24/7 call center with this vendor, they will be accessing a server in our network through the VPN to provide customer service during after hour periods.We have a problem however, with an application that is hosted by another vendor that is critical for our regular company call center. Access is reached with this application through this vendor by way of IPSec VPN tunnel that is built in our company's Cisco ASA 5510. This application is accessed via Internet Explorer that goes across to access the application at the endpoint
I need to figure a way by which the vendor that will be running the 24/7 call center coming through their tunnel in our network to connect over to the tunnel on the vendor on my ASA. Im likely going to have to set some routing of traffic in my internal default gateway router for this to work.
I've got a client that recently got an ASA 5505. E0/0 is connected to the outside, E0/1 connected to the internal server (Win 2008). The ASA "local network" is 172.30.1.0/24; my internal network is 192.168.1.0/24. I'm able to connect from home through AnyConnect and get a proper address (which I've got a pool of 172.30.1.64/26 assigned for VPN users), but no traffic from my computer will go to the internal network, nor will the internal server (or the ASA for that matter) can't talk to my VPN'd computer.
On the firewall settings on the ASA, I've got it all open: any/any on both inside and outside, just to try and get anything to go through. I've even got split-tunneling working, but not traffic-passing! The config is below (redacting local AAA users).

View 7 Replies View RelatedWe've got a fairly plain-vanilla VPN configuration on a C3660 router running IOS 12.3(26) so that our employees can initiate VPN sessions to our office using their Windows or Linux workstations. In a typical windows L2TP VPN configuration, the default route is set to the VPN server, and no other routes are passed to the clients, which means that if the client disables "use default route" setting, even getting to the office network fails.
I know there's a way to do this, but I haven't found it yet. What I want to do is pass local routes to the client so that only those routes transit the VPN, and permit the clients to use their own default routes.
I've been tasked with retiring a VPN Concentrator 3000 and replacing it with an ASA 5520. I'm trying to get a handle on how to set up the NATs and ACLs, since most of my experience is remote access VPNs, not site-to-site. Plus I've not configured a VPN 3000 in about 6 years so I'm having to re-learn a lot of the interface.
The VPN 3000 has a feature called LAN-to-LAN NAT rules that basically allow you to NAT an address on your internal network to an address on the "local" network for the LAN-to-LAN connection so it can then go through the tunnel to the remote side. The config looks something like this in the VPN 3000: [code]
Which looks to me like a "Static Policy NAT" in ASDM. So I set one of those up, that should be translating 172.16.3.151 on the inside interface to 192.168.200.151 on the inside interface (yes, the same interface) which should then (logically) be picked up as "interesting traffic" by the crypto-map and sent across the VPN tunnel. However, that doesn't seem to be the case - both the "packet trace" in the ASDM and traceroute from the source workstation show the packets getting to the inside interface, and then passed right out the outside interface to the internet router (which then drops the packets as they're a private IP).
what else do I need to do to make the crypto-map pick up the NATted traffic?
I am about to pull my hair out. I have a 1841 router at one end with 3 ASA's for teleworkers working great. I'm connecting a 4th one that I can not get to work for the life of me.

Am I totally overlooking somthing? I must have rebuilt this a dozen times.

I am facing a very big problem with site to site vpn on cisco 2900 ios.
I configured the vpn and when i ping from router itself to destination ip with source as lan interface , VPN works, no problem.
but when i connect any computer directly to router's lan interface to initiate traffic , it doesnot work at all. and on computer's lan i see yeloow sign.
mtu is 1500, speed is auto (I tried changing also) , duplex is auto ( i tried changing also) , through firewall on pc should not affect but still i disabled it.
since their is no problem with vpn config as vpn comes up when i initiate ping from router itself but i dont know why it is not working from lan.
do we need any inspect icmp on this router also ? or any policy modification to pass traffic across the interfac on router is required ?

Also I'm confused by the ports shown above since I was expecting to see 1433/1434 in there...seems this is a factor in the traffic never getting to the SQL Server to process the request?
