I plan on using PIX 515e as VPN concentrator for remote clients to access my dmz network. The config of pix is as follows:

For remote client i use cisco vpn client 5.0.07
Clients can connect just fine, but can't ping office-dmz interface (which i expect should be possible) and pix cant ping remote client (printing "?" - unknown packet type), besides when i see stats on client there is 100 byte increase in recieved traffic for every ping from PIX.
Also for connected client created strange, in my opinion, route:
S 192.168.104.100 255.255.255.255 [1/0] via yyy.yyy.yyy.yyy, outside (yyy - is default gteway)
When in my opinion it should be like 192.168.104.100 is directly connected, Virtual1234
So the question is is my problem related to ACLs? (can't ping)
Or is it IPSec related? (Unknown packet type may mean that something wrong with decrypting echo_replies on PIX)
Or is in a routing problem? (Strange route to client)
Or is there something else that i'm missing complitly?
