Has anyone else had an issue where they are able to sucessfully establish an IPSEC SA between a private subnet at Amazon and an external network, but no traffic passes until traffic is initiated from the UTM/AWS side of the tunnel?
In other words, while the remote partner sees the tunnel come up successfully, if they try to ping my side of the tunnel, they get no response UNTIL I ping a host on their end of the tunnel.
After that, traffic can flow in either direction... it just seems that the remote end is unable to initiate the connection.
Not sure if it's relevant, but the remote party is using a Checkpoint firewall/vpn device.
Curious if anyone one else has run into a similar problem with the UTM9 appliance in other environments or if this is something peculiar to using it within Amazon's Virtual Private Cloud or ????
thanks
