IPsec site to site VPN with problems

RouterOS Beginner Basics
1

Hello Everyone,
I would first like to say I love the Mikrotik product and I am learning a ton working with these products. Now on to the problem. I am having a problem connecting site to site VPN between two RB2011 devices. I can get the tunnel up and can ping the routers form the opposite router across the VPN, but I can only ping devices on the subnet behind one of the routers. The other subnet is accessible across the VPN. I created the VPN following Greg Sowell’s video.
Both of the routers have been upgraded to 6.33.3.
Any ideas on where I should start looking?
I will list any information from the router that will be helpful.

Thanks you for all your help!

Which kind of tunnel did you use?
I tried Greg’s IPsec tunnel and could not ping any IPs behind the router at either end, so you’re ahead of me.

I used an IPSec tunnel. I have been scouring this forum and the internet for any answers, but so far no luck. I feel like I’m so close.

I know what you mean about being close.
I found a youtube video that appeared to have PCs on each Mikrotik that could ping both ways, I can’t find it now.

I’ll post my rules so you can compare and see what I’m missing since you’re a step ahead of me.

I managed to get to the point you did, I could ping from my 192.168.90.0/24 network to the RB750 at 192.168.91.1 and a win 7 PC at 91.25.

Neither the win 7 PC nor the router could ping a win 8 PC at 192.168.90.25. The win 8 PC could ping 91.1 and 91.25. I ran windows update on the win 7 PC and after it rebooted I lost the ability to ping it or control it with VNC.

Thinking it might be a win 7 problem I put a win 8 PC on that router at 91.24. Both PCs can ping each other, the router at 91.1 and the other router at 90.1, but can’t see the PC at 90.25.
