Route is not working until ping command

[HerrKlauss]

Hi, I have weird problem for me :)

I am routing local network (eth0) to VPN network (eth1)

Local network 10.25.1.0/24 - GW 10.25.1.1
VPN network 10.11.12.0/24 - GW 10.11.12.1

On VPN network is Cisco ASA on IP 10.11.12.2 - I have this as another GW setup in pfsense.

Static routes are set: 192.168.1.0/24 via 10.11.12.2

FW rules set from local network to VPN netork - everything can communicate

Pass * * * 10.25.1.0/24 to 10.11.12.0/24 * *

FW rules set in VPN network - everything can communicate to local network and everything can communicate via optional GW 10.11.12.2

Pass * * * 10.11.12.0/24 to 10.25.1.0/24 * *
Pass * * * * to * via 10.11.12.2

Everything looks fine, but commication is working only after I run ping to 192.168.1.X machine.
Ping is working well, and after ping is working everything, but if I will not use ping first, no communication.

Can anyone explain me, what is causing thins and how i can fix it?

Thanks :)

I think the problem can be PROXY ARP.

On the Cisco ASA is proxy arp enabled.

How is possible enable or check if proxy arp is working on pfsense?
