Wireshark-users: Re: [Wireshark-users] Help With EPS/ISAKMP - Email found in subject
Hi,
Thanks for replying.
I was just shown the ICLs and for troubleshooting purposes, IP, UPD and
TCP have been allowed from ANY interface in the DMZ to ANY interface on
the trusted network. Is there anything else that could be causing this?

Sound like an ACL or firewall between the DMZ and the other network
dropping
ESP.

Subject: [Wireshark-users] Help With EPS/ISAKMP
Hi,
I was hoping someone could help me with this issue. I have configured
IPSec on two Windows 2003 servers using certificates as the
authentication.
If I run wireshark from one of the server while having both servers on
the
same network, I can see a bunch of ESP which indicate to me that the
traffic
is encrypted between the two servers. If I move one of the servers to
another network (DMZ) and try to communicate with the server located on
the
trusted network, I can't and instead of getting ESP packets all I see is
ISAKMP packets. I have not change anything on the IPsec except the ip
for
the server that has been moved to the DMZ. The trusted network as a
192.168.10.X subnet and the one on the DMZ is 192.168.20.X.
If I remove IPSec I can communicate from the DMZ to the LAN as intended
which indicate routing on the firewall is working fine. I know it is
kind
of confusing, but I'm trying to figure out why WireShark shows ESP
packets
when the server is on the LAN and ISAKMP packets when the server is
moved to
the DMZ.
Thanks,
Josue
