Gus,

If you notice, the host that is getting authenticated is 10.1.1.2.
However, the traffic destined for the internal network is from
138.88.46.143 (pool-138-88-46-143.res.east.verizon.net). You might get
through by either forcing IKE over TCP and/or UDP encapsulation on the
client side. This is done the in the Tools>Configure Connection
Profile>Advanced tab of the SecuRemote software.

Good luck,

Chris

Subject: [FW-1] problems with SecuRemote

I am running Check Point NG FP 3 on Linux 7.3.  I am having some
problems getting the client to site VPN to work.  I have the following
rules in my rule base before the stealth rule:

any -> no-fw1 -> any -> fw1_pslogon, FW1_topo, IKE, ESP,
VPN1_IPSEC_encapsulation -> accept

all users@any -> encryption domain -> if via RemoteAccess -> any ->
accept

My SecuRemote client can authenticate and connect to the site and
download the topology.  However, when I try to access a server in my
encryption domain, I fail.  When looking at the logs I see a drop on
IKE_TCP directed at the system I am trying to access.  I have attached
the logs.  Have a setup something wrong with my topology or encryption
domain?  Any help would be appreciated.  Thanks!
