Transparent TCP Proxy
Has anyone used a transparent TCP Proxy solution as a performance enhancement tool (via caching or buffering)?
Does Cisco has anything? WAAS looks the closest but it more like a point to point solution (wan acceleration). I am looking after something like a PROXY (device in the middle).
Thanks
Hello Tivig,
look for WCCPv2 it allows one or more routers to redirect to a group of web caches
It is supported also on multilayer switches and it is not limited to WEB traffic
see
http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/31sga/configuration/guide/wccp.html
Hope to help

Transparent local proxy on PC - possible?
Hi, Is it possible to write a transparent local proxy? And if yes what approach / classes would one use? That is, write an application or service that would automatically pick up any requests heading outbound for Internet access (via a site proxy server in a DMZ or direct too if possible) then proxy them out to where they were heading. Ie to enable stats etc to be picked up.

How to determine if extend TCP proxy isn't running?
I've setup a Coherence cluster using nodes Coh-A and Coh-B. I have a TCP proxy running on both the nodes on port 9098.
My application is able to the talk (i.e., both get and set) to the cluster through the TCP proxies. All is fine when the coherence servers are up and running. I was curious to see the behavior of the system when coherence servers are down. My requirement is such that, it should have no impact on the system if coherence is down. The application should instead bypass Coherence and go the database. But this isn't happening (logs below). Is there any way to check if the coherence server is reachable (up and running) before trying to access the cache from the application code?

Best Performance: HTTP accelerator or generic tcp proxy
Hi,
We want to publish an application based on HTTPS. ( vmware view). Which would be a better choice, the HTTP accelerator, or the Generic TCP proxy, in terms of performance (lowest latency) ?
Kind regards,
HenHi,
I am unable to identify a bottleneck.
The proxy is generally performing fine, only the vmware view connection through generic TCP proxy shows a delay.
Kind regards,
Hen

The tuneup settings are from Novell, and they work together with proxy
settings to allow the proxy to work faster, and handle heavier loads.
Have a look at the proxy console statistics and see if you can get an
idea if there is a bottleneck somewhere. Perhaps disk I/O. Perhaps a
DNS server problem (check proxy console option 4).

Generic TCP proxy: how to create Access rule ?
Hi,
I have configured a Generic TCP proxy on the public address, port 6300 of our bordermanager server that points to an internal server 192.168.10.148 on port 80. I have configured the filter exceptions for port 6300.
I have also tried to create an ACL rule to give everyone on the internet access to the Generic TCP in different ways, but I'm unable to succeed. I can see in the proxy statistics, number of ACL denials increasing each time I try to connect so the problem is in the ACL rule.
The rule I think should be right but isn't working is the following:
Allow:
source: host Ip Addresses:
IP: equals any (the Internet)
Destination: Host IP addresses:
192.168.10.148 (the internal server)
Origin server port:
6300 (the port on the public interface on which the Generic TCP proxy is listening).

New parameter "timeout tcp-proxy-reassembly" in ASA 8.2
I couldn't find much in the config guide or web site for this. Can someone tell me which situations this would come into play? Here is the CLI help:
"Configure idle timeout after which buffered packets waiting for reassembly in tcp-proxy are dropped"Hi.
I've had a very interesting discussion with a TAC engineer about this command.
The engineer mentions that, with this command, ASA behaves in the following way:
When the ASA receive a fragmented data, it puts the fragments in the buffer to be able to reassemble it and then sent it. When the buffer exceed the limit, the ASA start dropping the reassemble packets so the reason for the packet drop is always the buffer limit exceed . by using the command “tcp-proxy-reassembly”, the ASA wait for an idle time which is determined by this command, the reason why we need this idle time is that the ASA after dropping the fragmented packet still keeps the connection in the conn table open waiting to reassemble the fragments and send it , but this will not happen as the fragment was dropped , so this will keep the connection in the conn table and exhaust the ASA memory by a lot of connections that are not really used. After dropping the fragment the ASA waits for the timeout specified by the tcp-proxy-reassembly to delete the connection from the connection table.
So in summary the ASA uses this command not to delete the fragment after the timeout , it uses this command to delete the connection after the drop of the fragment (which is caused by the buffer limit) with the time.
So keep in mind when you use it.
Best regards,

My ISP has a bad configured proxy under my connection, filtering HTTP (80).
This means that many sites report me as banned, even If I never visited them. I wanted to know if exists something like a generic tcp proxy, to send all my conections there.
I own a VPS server on lineo (london datacenter), and I have the idea of turning it in my personal proxy. Can I do it with iptables rules?
I know the existence of squid, but I've heard its only HTTP, and also a madness to configure.
suggestions?A VPN set as the default route would probably work. I imagine there are instructions on the wiki for this.
You can also use tsocks + SSH. There is an option to force tsocks to load with every program. -
HTTP failed - Transparent web proxy
Hello,
I developped an application with Flex 3 B1, it works at my
home but when I tried it in my office I have this type of message
sometime
code:
Channel.Call.Failed
Message:
error
Detail:
NetConnection.Call.Failed: HTTP: Failed
Sometime the application works, sometime not... I think this
is a web proxy problem. I called the person in charge of this and
for him some program cannot works with a transparent proxy.
Somebody have the same problem ?
Best regards,
MarcThank you Ken for you whitepaper.
I read the configuration and it is mentioned that the IronPort and clients are not on the same interface (segment). I also read that the IronPort Appliance and clients must be on the same ASA interface to avoid passing trough the ASA itself again.
Which of these two is right ?
In my architecture I'm not able to set the IronPort on the same interface as clients (2 differents interfaces and subnet).
I attached a document explaining the architecture
My bad I saw that the WSA and clients are on the same ASA interface in the inside networks. Still, in my configuration is it possible to enable WCCP ?
I also so that it is possible to implement a route-map which perfrom PBR by changing the next-hop ip for specific traffic but this function is not avalaible on ASA as i heard. Can anyone confirm that ?

Extend TCP Proxy vs. Client load balancing
I am unclear how proxy and client load balancing interact with respect to custom address providers. If I define my own address provider, and I do NOT set the load-balancer parameter to client in the client configuration, will the proxy still do load balancing of connections as described in http://docs.oracle.com/cd/E24290_01/coh.371/e22839/gs_configextend.htm#BEBCICDA ?
Edited by: user5179040 on Mar 23, 2012 9:43 AMHi,
The <load-balancer> element is only configured in the <proxy-scheme> and not at the client side. This parameter "proxy" dictates the proxy to use the specified strategy for load balancing client connections across proxies. The parameter "client" offloads the responsibility of load balancing to client across proxies or randomly select proxies.

Upgrading from 8.4 to 9.1 issues (Transparent firewall)
Firewall is in transparent mode. At this time permit any any on trust to untrust and untrust to trust. It works great in 8.4; when I update the version to 9.1 it blocks all traffic yet nothing shows up in the monitoring mode. Downgrade to 8.4 and all is fine again. This is the simplest setup at this time and have it running in a lab. ICMP is blocked. All traffic is blocked and only occurs in 9.1

PC not getting IP in transparent ASA
Hi everyone,
ASA 505 is connected to layer 3 switch.
ASA is in transparent mode.
Layer 3 switch has SVI Vlan 20 and also it has dhcp server for vlan 20.
PC connected to transparent switch is not able to get the IP address from layer switch.
I have config the ACL on outside interface of ASA to allow the DHCP reply coming from Switch.
When i assign static IP to PC connected to port eth0/1 of ASA it works fine.

It worked great as always.
I got this ASA Security plus license few days back so trying to learn some concepts in home lab.
Need to undertsand the reason for these 2 ACL
1>access-list OUTSIDE-IN permit icmp host any echo
i already have ICMP under global policy so why we use the above ACL?
Also this ACL has hit counts to 0
2>when we allowed ACL to allow BootPC reply from any host to broadcast address then we we need this second ACL?
access-list OUTSIDE-IN permit udp host 192.168.20.0 255.255.255.0 eq bootpc
This ACL has also hit count to 0
Thanks

Hey all,
I'm trying to understand one thing with regards to transparent FTP proxy (via WCCPv2) and passive-mode FTP.
I realize that ACNS and routers have a special service group "60", which is used for native-ftp. However their documentaion is suspiciously lacking any technical details with regards to what traffic is sent to the cache-engine.
What I was looking to find out is:
When WCCP negotiates what traffic to redirect, typically the cache-engine tells the router what ports to redirect. Knowing that passive-FTP uses dynamic ports, does "service-group 60" somehow force the WCCP router to send all TCP ports to the ACNS cache-engine? Or is WCCP somehow stateful enough to only send the dynamically negotiated passive ports (which is hard to believe)?
Thanks for any and all help!The WCCP ftp-native service in ACNS redirects TCP traffic destined to ports 21 and 40020. Intercepting port 21 gives us the FTP control connection. In the event that the client requests passive mode, ACNS tells the client (over the control connection) to establish a connection on tcp/40020. Since this port is already defined as part of the ftp-native WCCP service, this gives us the data connection as well.
If you're interested in checking what protocol/port(s) are defined as part of a WCCP service group, you can use the commands:
show wccp services detail - Command on ACNS and WAAS devices
show ip wccp service - Hidden IOS command, where is the numeric service ID for the service
If you have any additional questions, please let us know.
Regards,
Zach
