No acess with only ping and smb - vpn ipsec site ti site

Fotit

Hi all ,

Today i have weired problem !

I have vpn ipsec connection between HQ and BO

There are few protocols allowed between the two LANS, but all access are initiated from HQ like RDP, Ping or access th share folder (SMB)

So everything working fine, until a few days ago..

I can't access to only one computer in BO from HQ, using ping and SMB. But RDP access work fine

all acess in the same BO LAN work fine to this computer ( ping, smb ...), so the computer doesn't block traffic

I haven't made any changes to the rules

I didn't understand why these only two protocols to this computer

Because also all traffic work fine to others computers (X,H,Z)

look at picture please

    Hi Fotit, 

    Both logs are reachable. Have you tried the other way around?

    1. Try to ping/SMB from the PC Y to PC beyond FW 

    2. Compare logs and settings from other PC

    3. Recheck the setting of FW policy for all PC's on remote

    4.FW & Filesharing on the Local PC

    5.Restart the PC

    If both firewalls only show "allowed" for these traffic, i would think it is a client problem at Y.

    Maybe the local firewall, the AV/EndpointProtection, or other..

    I would take a packet capture at HO and BO-Firewall with capture filter set to host=y
