site2site VPN Drops RDP

Hello together

we have a Little (i hope its Little) Problem here.

We have a site2site IPsec VPN Tunnel to a Sonicwall.
The Tunnel starts without Problems.

The Remote Location can ping our local Hosts. but cannot do a RDP Session.
our FW logs this with a SYN Default Drop by Rule 60002.

LOG:
2015:10:27-14:07:16 tj-fw1-1 ulogd[14418]: id="2001" severity="info" sys="SecureNet" sub="packetfilter" name="Packet dropped" action="drop" fwrule="60002" initf="ppp0" outitf="eth2" srcmac="00:1a:8c:f0:68:a2" srcip="10.33.0.1" dstip="192.168.135.110" proto="6" length="52" tos="0x00" prec="0x00" ttl="127" srcport="15597" dstport="3389" tcpflags="SYN" 

The auto firewall rules are there.

What i did so far:

Did the FW Rules manually on pos 01
Disabled appControl
Disabled IPS
and some other things.

Nothing worked.. Anyone have an Idea?[:S]

Cheers
Teo

  • Good catch, Teo.  Take Scott's advice to heart.  It wouldn't hurt to review #3 through #5 in Rulz.
