Site to Site VPN to multiple external Gateways/Partners

[gracemaina]

Dear Community,

I have multiple site to site VPNs with different organizations. The VPNs were working fine until recently when only one VPN comes at a time.

Am running CheckPoint 13500 on R80.30

Please help.

I don't understand what you mean by "only one VPN comes at a time."
What is the exact behavior?
What do you see in logs?
What changes were made in your rulebase or on the remote end from the time this started not working?
