I am running version 6.6. I got passed the timeout errors, and NAT-

traversal errors on the Sonicwall. Now on the pix, when I ping
from a host on the 192.168.2.0 network to a host on the
192.168.10.0 network the following is my debug
from the PIX:

scenario for site-to-site VPN
192.168.2.0<---->PIX<----------->SONIC<-------->192.168.10.0

pixconfig i
sysopt connection permit-ipsec
crypto ipsec transform-set halo esp-3des
crypto map test 10 ipsec-isakmp
crypto map test 10 match address NONAT
crypto map test 10 set pfs group2
crypto map test 10 set peer 210.4.56.9
crypto map test 10 set transform-set halo
crypto map test interface outside
isakmp enable outside
isakmp key test address 210.4.56.9 netmask 255.255.255.192 no-xauth

no-config-mode
isakmp policy 10 authentication pre-share
isakmp policy 10 encryption 3des
isakmp policy 10 hash md5
isakmp policy 10 group 1
isakmp policy 10 lifetime 28800

Any help you can provide, I would be grateful! TIA - Sean
