IPSEC remote access broken in 2.03

Description
In pfSense 2.0 through 2.02, my configuration for remote IPSEC access (like my iPhone) worked fine. IPSEC with Mobile client setup and firewall rule allowing all traffic to pass-through worked fine. The same config in 2.03 does not work. There is authentication and the VPN is established, but no traffic works. Going back to 2.02 with the same config works fine.

There is not nearly enough information here for a valid bug report. Include details about your exact config (every option you have set), how the clients are configured, a copy of your /var/etc/racoon.conf and so on. It's better to review/discuss all of that on a forum post before opening a ticket. If you have already done so, include a link to the forum post here.

I didn't get any feedback so I opened a ticket.
I used best practices and followed the WIKI to setup the VPN, so it should be easy to duplicate, but I've uploaded a sanitized config as well. Config is a working version on 2.02. A simple update to 2.03 will make that portion fail. (Since the VPN technically does work, it might be a firewall bug.)

Still not enough information. Most importantly we need the IPsec log entries (I forgot to mention that previously) from when it was broken.

You should have enough to re-create it on a pfSense box, but attached is the info you requested. Also, when the VPN connects the SAD tab shows data in the iPhone-to-pfSense direction, but not the return direction.

I used your exact IPsec config (aside from fixing the lifetimes to match the documented suggested values), and I am able to connect and reach items on the LAN behind my test VM running 2.0.3 (amd64) from an Android client.

I don't understand why it doesn't work for me in 2.03 - no config changes whatsoever between 2.02 and 2.03. I also just set up a Cisco VPN client (classic IPSEC) on a Windows XP virtual and have the same issue. Bytes sent from the Windows client, none received back. Both the VPN client stats and the pfSense stats mirror the same problem.

Cisco VPN client is known to be broken when connecting to pfSense (and it's a violation of their license to do so using the Windows Cisco client), use a known-good client such as Shrew Soft, or the Android/iOS client for testing.

same Problem since PFSense 2.0.2 with Android 4.1.2, 4.2, iOS 4/5.
Downgrade back to 2.0.1 and everything is fine with the same configuration.
I'll upload config after made a fresh instance with IPSEC only.

Not sure if it matters, but I am on an ALIX device. I have since moved back to 2.02 because I cannot afford the downtime. I will see how 2.1 works when I move to it. Thanks.
Updated by Micha Ch almost 11 years ago
We're using VMWare PFSense. Upgraded to 2.1 but still no luck with mobile vpn.

Mobile IPsec works fine in general in 2.1x versions. 2.2 changes out ipsec-tools which will change everything any edge cases in this thread might see, so no point in keeping this.
