IPSEC Site to site conneted

Yunus Abass Ibrahim

I Need  help regarding my ipsec. I have two sites HQ and remote site. The firewall is connected through ipsec. I have set both inbound and outboud rules.

But am still not able to ping each end of the firewall or to remotely access resources at HQ. Kindly advice .

    After disabling NAT-Rules ... if the problem stays existent (there are no hits at the NAT rules, so i think it is not source of the problem)

    Is there an additional firewall (or other restricting router) in front of one of the firewalls?  (Problems seen with Cisco - IPSec Inspection)

    XGS at both locations? Which version do you run at the systems?

    There is an IPSec change, which my generate problems you describe.

    (Tunnel is up but no traffic through tunnel)

    I would recommend:

    Packet capture at both sites. with filter = both external ip's ( BPF-String:  host xx.xx.xx.xx and host yy.yy.yy.yy  )

    What type of packets do you see ?? (IKE=500  && ESP or 4500 ??)
