I'm sure there are other options however I have had this problem several
time the last few weeks with my new data center.
My problem was solved when I told the unix admin's to check reverse DNS
and to try turning off the firewalls, after that I was good.
I have however not seen the problem with my actual "cisco configs"
Good Journey

hi, all,
I have a real world problem that I am scratching my head to find the
root
cause. We have a local data center at site A and a remote backup
server at
site B, site A and site B has its own service provider, the
connection
bandwidth is well above 50M in either site, traffic will traverse a
GRE/IPsec tunnel which is configured between two 2800 routers, both
routers
have hardware accelerated IPSec encryption/decrytion module
installed.
It is interesting that traffic from site A to site B is extremely
slow,
performance is only around 10s packets/second, but FTP transferring
data
from site B to site A is reasonably fast, which is around 8Mb/sec. I
am
pretty sure service provider of site A is not rate limiting incoming
traffic
(even it does, noway they will rate limit to 10s packets/sec). What
could be
the root cause of such poor performance, any server experts here can
give me
a clue?
Thanks,
Jian
