I have the following problem and hope that someone on this forum can help me.
We have a customer who is using a SonicWall TZ170 (OS Standard), Now our requirement is to setup a secure connection to this customer. We are behind PIX (OS 6.3); we don’t want to create a site-to-site VPN between the PIX and the SonicWall but need to use L2TP – which the SonicWall handles. I have setup the SonicWall for L2TP access and I can connect remotely using L2TP from a MS XP Laptop using a PSTN dial-up.
Now my problem is when I try to connect to the SonicWall using the same L2TP setup from behind the PIX, I can not get access – the session just times out. If I check the PIX connection table I see that PIX has setup a translation from the internal IP to the external IP (SonicWall Public IP address) on port 500 – BUT no flags?
Unfortunately for me, our senior Firewall expert is on his hols and I need to get this up and running ASAP.
Can someone from this forum be kind enough to help me?
Thanks in advance.
