I plunked down the money for access to Cisco's downloads.
It turns out the problem is due to a known problem with the old IOS.
The problem did not go away with then new T24 IOS, but was substantially improved.
They sent me a document that shows with full inspection rules the 871 is only...
Shaffer,
Interesting thought.
When you compare your download speed at speedtest.net both with an inspection rule and without any inspection rule. Is there any difference in your measured download speeds?
If I understand your problem correctly, you should have a normal download speed...
Quadratic,
My apologies, they seemed to be the same problem according the symptoms and history.
Before I run off and create another thread, could you provide more information as to why they are different problems?
Baddos,
I don't know where you got the idea that this is a threat, it is a request for help.
1. Although the setup I use is more complex as I stated, I posted the minimal setup under which the problem occurs above.
2. The one-line "deny any any" inspection rule can be changed to "permit any...
Shaferbus, Baddos,
I am having identical symptoms to Shafer.
I have reset the router back to factory specs to no avail.
I suspect if it is a fragmentation problem, it is a low level memory addressing scheme that has no way to recombine it's addressing of memory into contiguous blocks, even...
Baddos,
ANY inspection rule causes the problem.
The problem persists even if I REPLACE the "deny any any" rule above with "permit icmp any any echo-reply" with no logging- the bandwidth still drops to single digit bytes per second.
If I remove all inspection rules, the bandwidth is normal...
Schaferbus, Billy, Rassoul,
I tried what you said Billy, to no avail. I suspect, but don't know for sure, that Flash fragmentation is not reset on erasure.
This is a repeatable occurrence, even with a plain-jane setup from a router resert shown below. Just add a minimal inbound inspection...
My cisco 871 router is recently suffering identical symptoms.
The moment an access-list is specified on the incoming side of the outward facing port (FastEthernet4 in this case) the download speed quickly drops to single digit bytes per second. Remove the ACL and the download speed is back to...
