unusual hub-and-spoke addressing scheme.

I have an hub and spoke configuration.

ASA5520 is the hub, zyxel are spokes.

Due to limitation on zyxel, I can only setup a single line remote network/local network.

the two branches must talk each other, and with a server on central site.

I wanted to perform the following.

1) zyxel 1 use local: 10.15.1.201/32 and remote 10.15.0.0/16

2) zyxel 2 use local: 10.15.2.201/32 and remote 10.15.0.0/16

3) ASA has local 10.15.0.0/24, but uses 10.15.0.0/16 when establishing tunnels.

host on spokes can communicate to hub, but they cannot ping each other.

output is a packet trace from spoke 1 to spoke1.

it seems summarization made bad things to VPN rerouting.

any hint?

shall I make it work without creating multiple vpn sets?

TIA

Post the config of the ASA for reveiw - remove any sensitive information.
