- For this article, I used a Cisco 871W router that's running Cisco IOS Software, C870 Software (C870-ADVIPSERVICESK9-M), Version 12.4(4)XC2, RELEASE SOFTWARE (fc1). Specifically, it has this IOS.

I was setting up a Cisco 877 router on an ADSL 2 BT Broadband connection this week and came across an issue when downloading large files from the Internet. With the router configured, and connected everything appeared to be working OK. The ADSL connection was stable, and the VPN tunnel was up and transferring data happily. I performed a few more checks, one of which was to run a speed test using speedtest.net. The test started fine downloading at around 6.5Mb per sec but when it got halfway through it stalled and didn’t complete. Following this I tried to download a 600MB ISO file using my web browser. It downloaded about 100MB and then stalled. Subsequent attempts produced similar results, although sometimes I could only download a couple of MB, and sometimes 50MB to 100MB, but at some point the download would stop and not get any further.

Interestingly, I didn’t seem to get this problem when transferring files over the Site to Site VPN connection, as I transferred around 400MB of data across the VPN without issue. This made me think that it it could be something to do with traffic inspection on the zone based firewall. I did a little digging on the Internet, and found some information relating to out of order packets on Cisco equipment using the Zone Based Firewall. Other reports suggested that if you remove the zone based firewall, downloads proceed normally. It seemed quite a few people have had the same issue that I was having, and there were a few steps that could be taken for verification.
Firstly, in configuration mode set the logging level on the device to ‘debugging’:
router(config)# logging buffered 51200 debugging
Next, turn on logging of dropped packets:
router(config)# ip inspect log drop-pkt
At this stage if you are running in a telnet session you can use the following command to output debug messages to your session:
router(config)# terminal monitor
Alternatively, you can view the log file after testing by running:
router# show logging
After adding the commands to log dopped packets, I kicked off the ISO download again and waited for it to stall. Sure enough after it stopped downloading I got the following message logged (IP addresses have been removed):
%FW-6-DROP_PKT: Dropping tcp session X.X.X.X:80 X.X.X.X:52334 due to Out-Of-Order Segment with ip ident 0
Apparently the zone based firewall has a bit of an issue with out of order packets, but fortunately support for out of order packets has been introduced in IOS versions 15 and above. This 877 router was running IOS version c870-advsecurityk9-mz.124-24.T7.bin. There was only the standard 24MB flash in this router so I upgraded to IOS version c870-advsecurityk9-mz.151-1.T4.bin.
After applying this upgrade the issue was fixed, and downloads proceeded normally.
