Cisco :: Full Access To Everything Since The Tunnel Is Set To Bypass Interface ACLS?

Nov 23, 2011

I have ip phones at the remote location that connect into the phone switch(it's a nortel cs1000 system) over the tunnel. Internal calls work just fine, however when somebody calls from the outside, or calls are made to the outside the connection is never finalized. Like if I call from my cell it rings the phones, but when I answer there is nothing but dead air.In the group policy for the tunnel, I gave the remote site FULL access to the phones vlan and vice versa...which obviously works since internal calls work fine. If I remove my group policy and give it the Default group policy which essentially gives that tunnel full access to everything since the tunnel is set to bypass interface ACLS, external calls work fine. So it's definitely related to the group policy.

The group policy is basicallyAllow remote site to X network/host on these ports no denies since it blocks whatever isn't specifically allowed. However since it can get the phone switch and it can get to the internet I'm not seeing why the calls aren't working.The only thing I can think of to try doing as well is remove the allow inbound traffic to bypass interface rules and treat it just like another vlan interface on the ASA. Create the rules on each interface for the remote site network etc and see if it works that way.

Cisco VPN :: ASA 5540 / Internet Access Is Slow When Running Full-tunnel

Aug 7, 2011

We have ASA 5540.  We setup Site-to-Site VPN and Remote Access VPN (Cisco VPN client).  If are running full tunnel on the Cisco VPN client, the internet access is slow.  For example, when we are running full-tunnel, the internet speed is 16 Mbps based on Speedtest.net.  When we go to Speedtest.net, some of the graphics do not load.  If we are running Split-tunnel, the internet access speed is 78 Mbps based on Speedtest.net and the Speedtest.net web site loads all the graphics.

Cisco :: ACLs To Limit Ports With Client - Based VPN Tunnel

Jun 16, 2011

I have a customer I've built a webvpn tunnel for.Users on this tunnel need to have http access to a server at 10.1.1.12 and nothing else.That's fine, but in order for name resolution to work properly they need to be able to send DNS requests to 10.1.1.9.I'm working with two different access lists, my non access list (nat 0) and my split tunnel access list. I can't specify ports in the nat 0 access list, but I did try writing my split tunnel access list as follows:

-access-list split permit ip host 10.1.1.12 172.16.4.0 255.255.255.0
-access-list split permit udp host 10.1.1.9 eq 53 172.16.4.0 255.255.255.0

When I do that users can access the 10.1.1.9 dns server, but they can hit it on anything (ping, 3389, etc.).I'm trying to figure out how I can limit them so they will only be able to pull dns but nothing else.They have the Any connect Essentials license, so unfortunately a clientless VPN is not an option. Is there some other access list I can interpose that will limit things the way I want?

Cisco VPN :: ASA5500 / TCP State Bypass For Traffic - Coming From IPsec Tunnel?

Feb 6, 2012

We have problems on central firewall with restricting traffic coming from remote office from IPsec. (The network sheme is attached) All branch offices are connected to central asa though IPsec. The main aim is to rule access from branch offices only on the central firewall, NOT on each IPsec tunnel According to the sheme:172.16.1.0/24 is on of the branch office LANs10.1.1.0/24 and 10.2.2.0/24 are central office LANThe crypto ACL looks like  permit ip 172.16.1.0/24 10.0.0.0/8 the aim is to restrict access from 172.16.1.0/24 to 10.1.1.0/24 When packets are generated from host 10.1.1.10 to 172.16.1.0/24 all is ok -  they are dropped by acl2 When packets are generated from 172.16.1.0/24 to 10.1.1.10 they are not dropped by any ACL - the reason is stateful firewall - traffic bypasses all access lists on a back path I thought that TCP State Bypass feature can solve this problem and disable stateful firewall inspection for traffic coming from 172.16.1.0/24 to 10.1.1.0/24, but it didn't work.The central asa 5500 is configured according to cisco doc [URL]

Cisco Switching/Routing :: 3750E / Applying ACLs When Routing Between SVI And Routed Interface?

Mar 12, 2013

Quick question here. Using 3750E series switches with multiple VLANS configured. These switches serve as our 'core'. I have SVIs configured for the different VLANs and add inbound ACLs in each of the SVIs to control traffic between VLANS. This switch also terminates a P2P Ethernet link which connects to our Colo facility. The port used for this is configured as an L3 port. I noticed today that I was able to send traffic across this L3 link that I thought should have been blocked by an ACL I had in place but it wasn't. So the traffic flowed from a port in say VLAN 20 across this L3 link (assigned with an IP address). Would this traffic flow not cause traffic to be checked against an ACL applied in the inbound direction on the SVI of VLAN 20 (int vlan 20)? Traffic does get checked when routing between SVIs. Why would it not get checked when routing between SVI and L3 interface?

Cisco Firewall :: ASA 5520 Not Passing Full Interface Rate Traffic

Apr 12, 2012

I have an issue where our ASA 5520 is impacting upload (from LAN to internet) speed. We have a 100Mbps SDSL internet link and only see around 45-50 Mbps on the upload when going via the firewall, download is around 90+ Mbps so that is acceptable. I have tested a laptop connected directly to the internet router and that give near on the 100Mbps up and down speeds, but if I put that laptop on the LAN or directly onto the firewall interface I only see 90Mbps down and 45Mbps up. I have check that the interface speeds/duplex on the firewall, switch and laptop are correct and also checked there are no errors on the ports. I also turned off the IPS and that made no difference. In addition I have checked the CPU during download/upload (max): CPU utilization for 5 seconds = 9%; 1 minute: 3%; 5 minutes: 1%
 
In theory the 5520 should be able to cope with this throughput:

Cisco ASA 5500 Series Model/License:    5520
Maximum firewall throughput (Mbps):          450 Mbps
Maximum firewall connections:                      280,000

Cisco VPN :: 2811 - IOS Tunnel Interface Keeps Going Down

Sep 7, 2011

I'm seeing on an IOS VPN Tunnel interface which keeps going down and then back up...
 
We have a Cisco 2811 acting as a VPN Hub router on the backbone, which connects to various client sites over VPN. Of the 7 VPNs configured so 6 work well and are generally trouble free. The VPN interface on the other VPN keeps going down ,multiple times throughout the day, just recently the client has been noticing loss of connectivity. The remote router is managed over the VPN so there is always some kind of traffic over it.

Cisco VPN :: ASA5510 L2L VPN Tunnel End Point Interface?

Feb 12, 2012

Is this kind of configuration possible? Can the VPN tunnel go thru the Firewall to another interface (DMZ) on it? And not to end “outside” interface.I have DMZ network in ASA5510 interface and I like to end the L2L IPsec VPN tunnel on it. The tunnel mas go thru the ASA from Internet via outside to the end point DMZ interface. The traffic is decrypted to that interface.  So the VPN L2L peer interface is the DMZ interface IP address, not the Outside interface IP address.

Cisco WAN :: ASR 1002F - Per Tunnel QoS And Physical Interface CBWFQ

Jun 5, 2012

I am preparing configuration (currently in lab) for Per-Tunnel QoS in DMVPN on ASR 1002F for one of our customers, and I came across one issue. According to restrictions for this feature, I cannot apply per-tunnel QoS in conjunction with interface based QoS. This means, I can provide shaping with hierarchical CBWFQ for each spoke, but I cannot guarantee anything on physical interface! What if there are services in native MPLS? I am also unable give reservations for BGP which is used on PE-CE link! How about monitoring spoke PE-CE links natively? I can only apply policy-map with class-default on physical interface. When I add anything related to queuing for that class (or any other non-default class) I get the message:
 
R1(config- pmap)class routing
R1(config- pmap-c)#bandwidth 16
service-policy with queuing features on sessions is not allowed in conjunction with interface based

Cisco Firewall :: ASA 5550 / RFC 1918 - Tunnel Terminates At Outside Interface

Aug 2, 2011

I've recently set up a LAN-2-LAN VPN tunnel to a 3rd party service provider who uses RFC 1918 private addressing internally and cannot perform NAT on their side of the tunnel.  In order to avoid conflicts with our address space I've had to implement DNAT for the address on the 3rd party network that users at my end must access.  The tunnel terminates at my end on the outside interface of an ASA-5550 running 8.4.2.  While the ASA has 8 interfaces at security levels between 0 and 100, DNAT only need occur for traffic flowing from inside (100) to outside (0).

The following (redacted) addressing applies:

Address of the server on the 3rd party provider network: 192.168.2.155

Mapped address of server as seen on the network at my end: 10.168.2.155

I've currently implemented DNAT using object NAT as follows:

object network remote-server
host 192.168.2.155
nat (outside,inside) static 10.168.2.155

This works as expected, however in examples and discussion I've seen, it appears that the typical way to configure NAT for this scenario is with manual NAT as follows:

object network remote-server
host 192.168.2.155

object network remote-server-mapped
host 10.168.2.155

nat (inside,outside) source static any any destination static remote-server-mapped remote-server
 
Is there any reason why I should consider using the manual NAT method rather than the object NAT method in this scenario?Are there any technical reasons why using object NAT in this manner should be avoided?

Cisco Firewall :: ASA5510 - Web Interface On NAS From Remote Site Across VPN Tunnel?

Dec 3, 2012

I have two routers on my internal network.

10.10.199.106 is a Cisco ASA5510.

10.10.199.108 is a Sonicwall NSA 3500
 
The sonicwall handles our site to site VPN tunnels.  The Cisco handles our client to site VPN connections.
 
I have a unit that points to 10.10.199.106 (Cisco) for internet access.  All other clients on the network point to 10.10.199.108 (Sonicwall) for internet access.The device in question, a Synology NAS, is using 10.10.199.68 as it's IP address.
 
I'm trying to hit the web interface on the NAS from a remote site across our VPN tunnel.  The IP scheme on the remote end of the VPN tunnel is 192.168.72.0/24.
 
Going through the VPN, I can hit every object on the network that uses .108 (Sonicwalll) as it's gateway.  However, I cannot hit the unit that uses .106 (Cisco) as it's gateway. 
 
I added a route statement (using ASDM) that routes all traffic destined to 192.168.72.0/24 to the Sonicwall so it can send it back down the VPN tunnel.  If I'm understanding routing correctly, this should allow responses from NAS destined for 192.168.72.0/24 to go back down the VPN tunnel.

Cisco :: ASR1002 SNMP Statistics For GRE Tunnel Interface Statistics

It seems as soon as we exceed some level of Bandwidth (~ 700-800k) the tool does not get the information.The OID I try to get are ifHCInOctets (.1.3.6.1.2.1.31.1.1.1.6) and ifHCOutOctets (.1.3.6.1.2.1.31.1.1.1.10) and some other interface statistics for both 64 and 32 bits. [code]

Cisco Firewall :: ASA 8.2 Getting ACLs Loss

Jan 23, 2013

I'm almost afraid to post since my stuff is so OLD!

The air card doesn't like my Compaq - occasionally crashes it. I thought to put the air card in a router to solve the problem and communicate with the router using the Cisco 350. Bought a Cradle Point router from my ISP and plugged in the Franklin.  Then spent the next 5 days trying to get the Cisco 350 to associate with the router.I now have a profile with the router's SSID in it that according to the ACU's status report is associated with that SSID. Problem is that there is no Internet connection.
