Cisco WAN :: Split Data Flows Over A Single T1
Nov 7, 2012Is it possible to split data flows on a single T1. Say 1 Flow on time-slots 5-6 and another data flow on time-slots 10-14. If one was data and the other voice would this work?

Cisco :: Manipulating Traffic Flows On The ASA?
Sep 19, 2011So I've just discovered the Cisco ASA is not capable of performing policy-based routing.
I am in a position where I need to manipulate traffic flows from the inside network outwards for TCP80 & TCP443 traffic toward a transparent proxy server while default routing the remainder of the non-matching traffic.
Can anybody think of a way to do this with the ASA? Would a destination NAT work?
For example:
nat (inside,outside) source static any any destination obj_any proxy_object service tcp 80 80 nat (inside,outside) source static any any destination obj_any proxy_object service tcp 443 443
Why would the ASA not support PBR?
Cisco Application :: CSS 11501 Not Dropping Flows If Service Is Down
Oct 14, 2012some misconfiguration (?) may be the reason for an undesired behaviour we are experiencing with our Cisco CSS 11501s. Balancing mechanisms work fine, however if a service transitions to the "down" state, the corresponding flows remain "alive" leading to a temporary outage of our service. Subsequent client requests are still being sent to the "down" frontend which is unresponsive.

Under "Specifying Hosts and Networks / Remote Network" i use not the external ip of remote Site, i use the internal networks ( 10.0.1.0 and 10.0.2.0 ).

Nov 30, 2011I have an ASA 5510 running version 7.0. I have a problem with an exchange server using a static map and its outbounc connectivity. It connects outbound through the global address even though inbound connectivity works fine through the static mapping. The recent changes are changing of the zero route through a different interface (there are to circuit connected to this ASA on different interfaces). So the idea was to get all workstations in the office using the global address and routing out through one circuit, and the servers connecting in/out through the other circuit. Shouldn't a static mapping ignore what the zero route is?
Here are what I believe to be the relevant configs.

So exchang2 server can be connected to from the outside properly via IP xxx.207.51.231/exchange2-outside, but all outbound connections from this server are going out via IP xxx.122.47.218/circuit-6mb as do all the workstations due to the global address statement.
Cisco Firewall :: 5505 / Asymmetric NAT Rules Matched For Forward And Reverse Flows?
May 6, 2013I am new to ASA's and have just configured my 5505 out the box with an outside (10.10.1.7) + inside (192.168.1.1) IP & NAT. The ASA has got a default route to another router (default geteway) thats connected to the internet. I have it connected this way so I can play and **** around with the ASA. My problem is when I try and ping a host on the ASA inside network (192.168.1.0/24) from the outside (10.10.1.0/24) I'm getting the following error: 5May 07 201316:38:36305013192.168.1.6Asymmetric NAT rules matched for forward and reverse flows; Connection for icmp src outside:10.10.1.22 dst inside:192.168.1.6 (type 8, code 0) denied due to NAT reverse path failure The recommendation from the syslog details is:"When not on the same interface as the host using NAT, use the mapped address instead of the actual address to connect to the host.

View 2 Replies View RelatedCisco :: Split Tunneling / ACL On ASA5510
Jul 16, 2011I just moved our vpn over to using LDAP/DAP instead of the previous RADIUS we were using before. First of all, the group policy split tunnel is setup for Tunnel Network list Below Network list has a group of networks named "split-tunnel" setup with all of our internal subnets in it. Which seems to be working fine, users are hitting internal networks no problem.Where the issue lies is surfing the web while they are connected to the VPN.I think I know what one of the the issues are, I'm just not sure how to get around it. I have a proxy server setup that all domain traffic goes through say 10.20.30.40. That is obviously on our internal subnet. Our remote users has a policy on their laptops set to where if they can see/get to the proxy server then it pushes all traffic through there, however if they can not, it goes straight to the internet. That way they can still surf the web when they aren't connected to the domain network.
With the new DAP vpn policies, it seems as though they are trying to go through the proxy but failing so all http traffic is getting blocked on their computer as I can still ping say google.com...just can't open the web page.In my SALES-VPN access lists there isn't any acl that allows any traffic to 10.20.30.40(proxy server) so there isn't any reason their laptop would think it could get to it correct?I can't put an access-list SALES-VPN extended deny ip any any log critical at the end of the acl list because then it doesn't show up as an option to apply to the DAP since the acls have to be either permit or deny, not a mix.Also, if I just create an ACL access-list DENY-VPN extended deny ip any any log critical and apply it to the DAP *after* the SALES-VPN ACLs thinking all traffic would flow down as in go through all the permit acls first, and then hit the deny acl after, it just blocks all traffic.It almost seems that some traffic that isn't specifically being permitted by the permit acls is still getting through which is obviously not wanted. However, if I try to rdp into a server that isn't specifically permitted in the SALES-VPN acls it doesn't work so I'm kind of at a loss..
Cisco WAN :: 891 - Split Internet Bandwidth
Aug 22, 2012I'm pretty new to this, and I've been trying to read up on what I should do. Here's my situation: we have a new 15mps internet connection coming into our building. We also have a new 891 router. We would like to devote 1.5mbs at the highest priority to one LAN which is just used for VOIP phones. We would like to allow one of the other tenants to use up (but no more than) to 5mps for their LAN, and we'd like to be able to use up to 13.5mps for ourselves if it's available, or at least 8.5mps (15-1.5-5=8.5).
From searching in here and reading the various articles on policing and shaping, I'm thinking that we'd want to set up Class-based weighted fair queuing on a per-interface basis, and have one interface connected to our VOIP switch, one connected to the other tenants switch, and one connected to our firewall. Does this sound like the right way to go? And would anyone have an example of a configuration which achieves this?
Cisco VPN :: How To Enable Split Tunnel On PIX 501

Mar 2, 2011I have an ASA 5505 configured using easy VPN connecting to our corporate ASA. The ASA5505 is configured for network extension mode with a routable subnet. The clients that hang off the ASA 5505 are DHCP and get their IP address and DNS settings from the ASA 5505. I have a split tunnel setup, so only certain networks go over the tunnel back to corporate. Local Internet browsing goes out the ASA 5505 to the ISP.
My questions is how to setup split-dns. i would like to have my clients query the ISP's DNS servers for Internet based websites and when they need to access the exchange server the query goes to our corporate DNS servers. I see a setting for DNS names under the group policy on the corporate ASA, but how does the client know which DNS server to use?
The clients receive a primary DNS server (ISP) and a secondary (Corporate DNS) from the ASA5505.

Cisco VPN :: 5505 Disabling Split Tunneling In L2L
Jul 25, 2011my company has used Split Tunneling for all of our VPN uses, however we recently purchased 2 ASA5505s for use at various jobsites, and have been running into problems with Local Network Administrators blocking certain traffic that we need to operate. They allow full VPN connectivity to traverse their networks, so we are able to use our LAN Resources over the split tunnel no problem.
We have it set up as a Dynamic L2L Connection, and this ASA is operating flawlessly minus the traffic being blocked upstream by the network admin. Our VPN topolgy is Hub & Spoke. Below is excerpts from our config on how the VPN is set up: [code]
What we'd like to achieve is being able to pass ALL traffic (LAN & Internet) through the VPN tunnel, then be processed by the Hub ASA (192.168.9.1) on the other end. I am guessing crypto map + routing would have to be changed?
access-list to_hq extended permit ip 192.168.101.0 255.255.255.0 0.0.0.0 0.0.0.0route inside 0.0.0.0 0.0.0.0 192.168.9.1Disable NAT on Spoke. Is this how I would go about doing this??? We need ip address dhcp setroute so our ASA can find the other end and form the VPN tunnel, and I am not sure how this would affect things. [code]
