default inactivity connection time out for A3(1.0) So by defult any tcp connection(http or https) will be timed out in an hour. [code]Was this change in the A4(2.0) code or is it still the same? I heard a TAC engg say that default inactivity timeout for http and https are now 5 mins that is 300 seconds.

We had an issue the other day where doing backups through the firewall (don't ask) caused the "control" session to timeout while the backups were still going on over the "data" connection. This broke the backup about two hours into the job. My first thought was that the backup solution vendor should implement some kind of tcp keepalive for the control connection. A packet capture showed they indeed were -- after 2 hours! Ah ha! Busted! How could they choose such a poor choice of TCP keepalive timer for their application that would not be compatible with the 60 minute inactivity timer that so many firewall vendors use (Cisco, Juniper, Checkpoint and Fortinet all use a default 60 minute inactivity timer for TCP)?
Well, a colleague of mine pointed out that there is actually an old RFC that covers this. RFC 1122. It says:
Keep-alive packets MUST only be sent when no data or acknowledgement packets have been received for the connection within an interval. This interval MUST be configurable and MUST default to no less than two hours.
Now I know that RFC is old (October 1989), but that's all I could find. Is there something that supercedes that? Maybe common sense perhaps? I understand not wanting to fill up your connection table because of mis-behaving applications, but I'm just looking for ammunition to use against the backup solution vendor. Surely they're going to point to this RFC.

what would be causing my management HTTPS session to a SF200-24 to suddenly timeout? I receive "The session has been timed out. You may log in again" few mins after logging into to switch.Sometime it happens within 45seconds, other times after 3mins, timouts are not consistent. And, i was not idle when it timed-out. My HTTPs idle time-out is set for 10mins.
I had a continuous PING going to managment IP, and it did not drop any pings when session timed-out.Interface stats are also clean. I tried IE, FireFox, Chrome and all are timming out.
I've changed the HTTP default idle-time out from 1 to 10 and my HTTPs stopped timing out. Management Access Authentication is cleary set for HTTPs, and the Idle-timeout for HTTPs was set for 10mins since install. Yet, adjusting the HTTP idle-timeout cleared the issue.

View 1 Replies View Relatedi have ACE 4710 appliance that terminate SSL and the connection to the servers is http.
The ACE (one Armed) is load balancing between two web servers and i am using stickness in order to take the connection on the same server based on cookie.I can access the website either by http or https., where on the web page there is a login credential to access using username and password.
When i access the website using https everything works fine and i can login to my account in https mode.When i access the website through http and login to my account the URL is redirected to https...normal because i am using action-list to rewrite the http into https. But when i exit the browser and access the website again using http it is not redirected to https(although i see that i am still login into my account i can see all the inforamtion in my account).
The customer wants the connection to be https even when i exit the browser and access the website again (within short time before the cookie exipres)
We are using an ACE20 module running version A2(3.2).I have a question regarding IP stickyness and the timeout parameter.I found this in the "Server load balancing configuration guide" (in a section entitled: "Configuring a Timeout for IP Address Stickiness"):
"The sticky timeout specifies the period of time that the ACE keeps (if possible) the IP address sticky information for a client connection in the sticky table after the latest client connection terminates. The ACE resets the sticky timer for a specific sticky-table entry each time that the module opens a new connection or receives a new HTTP GET on an existing connection that matches that entry."
The parts in bold seem to point to the fact that the timeout is an "inactivity timeout" as the counter is reset on every new connection.The next section in the documentation is entitled: "Enabling an IP Address Sticky Timeout to Override Active Connections" and says:
"By default, the ACE ages out a sticky table entry when the timeout for that entry expires and no active connections matching that entry exist. To specify that the ACE time out IP address sticky table entries even if active connections exist after the sticky timer expires, use the timeout activeconns command."
This seems to contradict the previous statement.So my question is: is the IP stickyness timeout an "inactivity timeout" or not?

View 2 Replies View RelatedFor a CSS with a SSL module (performing SSL termination) - is it possible to impliment a redirect on https URL to send to equivalent http URL.If my understanding is correct, the CSS will do SSL termination and then use an http content rule on the resultant http stream as it is recursively handled by the CSS ? This would mean that the SSL module has no way of seeing/acting on layer 5 and above data (i.e. picking up on a specific URL) and can not itself issue a redirect - i.e. you could not associate a redirect statement or service with the following ssl content rule ? [code]The CSS would instead rely on a http content rule to impliment a redirect - i.e. you would have to associate a redirect statement or service to the following http content rule instead?
But if the CSS is already handling traffic for existing url... traffic that is going to cause a loop when a client goes direct to. url...I realise the requirment is uncommon / a bit convoluted, its one of those don't ask type scenarios - aimed at achieving a specific requirement.Would the ACE 4710 be able to handle such a scenario any differently ?

View 7 Replies View RelatedI have a CSS 11503 with a basic content rule for TCP 10000 going to a few backend servers. I was looking into the default timeout values for flows and when testing using telnet the flow didn't terminate as expected?
For example, i have no 'timeout multiplier' specified in the config and when i look at the output of 'show flow-timeout default' it tells me the default 16 seconds timeout is in effect for *. With that in mind, i telnet to the content rule vip on TCP 10000 and on the backend server using wireshark i can see the TCP threeway handshake. With no data passing i'd expect the CSS to terminate this flow after 16 seconds.. yet it takes exactly 128 seconds before wireshark shows the RST and the flow is terminated. 128 being 8 times the default 16 second flow timeout.
If i try to force the connection to close early by specifiying 'flow-timeout-multiplier 2' in the content rule, or even a multiplier of 40, it still waits 128 seconds to close the telnet connection.

I am just wanting to know the easiest way to deploy this? Is a certificate always needed on the ACE for each connection? In HA mode would a certificate be needed for both or does it replicate in some way to the other ACE?

I’m looking for some notes from the field guidance here from those that have much more deployment experience.
I have a GSS and an ACE, and its the ACE that's primarily giving me something to think about, in terms of placement and what mode to adopt.
The traffic flow will look loosely like this:-
Client---Internet---Firewall---GSS---ACE---Servers
Physically, it's like this. The RED line denotes a boundary, and pretty much anything North of that is not accessible to us, we simply have a L3 trunk between our switches and "their" switches (S3/S4) and talk using EIGRP.
There are other servers in the top tier, some that also require load balancing, some that don’t. Typically, I want to load balance HTTPS requests from the internet, to one of the 3 servers in the top half.
I’m not sure what mode to select, routed, one arm? What about placement of the ACE? At the moment, I’ve just configured 1/1 on it and made it part of the MG MT VLAN, it's S VI exists on the S1/S2 switches, so I’m open to change as it's still all in the lab.
if ACE SM in L2 mode need the default gateway? We're running v. 3.2a.

I'm running several game and file servers via a dynamic IP, which I unfortunately cannot change to a static connection for several reasons. I've solved this by using No-IP, which is a Dynamic IP resolution service. This solved the first part of my problem - I can give people IP's for their websites, such as myfreemusic.sytes.net and so forth, but they all HAVE to append their ports to the url - i.e.
site1.sytes.net:90
site2.sytes.net:91
My main problem right now is the game servers - I'm hosting games that default host to 25565, and though I can change the ports the server hosts from, I must give those who want to connect the ports at the end of their urls, i.e.
server1.sytes.net:25566
server2.sytes.net:25567
I know DNS is essentially agnostic when it comes to ports, so no solution there. And I don't think the game (Minecraft vis-a-vis bukkit) supports SRV records, and even if they did, I'd have no idea how to configure them. How can I resolve static urls redirecting to a dynamic IP by pointing them to ports?
To simplify the question -
How can I make server1.sytes.net resolve to port 25566, and server2.sytes.net resolve to port 25567 when the default port is set to 25565?
Since the ACE supports only static routing, when pointing a default route from the ACE what is your preferred method when using multiple 6500s with an ACE in each in a failover scenario to prevent just pointing at one 6500? Static route to an HSRP address? Multiple static routes on the ACE, etc?
