checkpoint authentication on external interface

I hope the list can help me out or point me in the correct direction.
In Checkpoint R65 splat when you turn ON Manual authentication, it turns ON port 259 and 900 on both internal and external interfaces. I was wondering if there's a way to turn it OFF on one interface and still keep it on the other. An example would be if you have an edge firewall and you don't want it to be visible from the outside but still need it for other functions. I tried to create a rule that would block anything from the outside to the firewall on those ports and that did nothing. Looking in tracker also showed nothing. I can connect to the login page but I can't see any logs. looking through the implied rules also showed nothing. So does anyone have any suggestions that would not kill my support contract? :) thanks Frank _______________________________________________ firewall-wizards mailing list firewall-wizards@... https://listserv.icsalabs.com/mailman/listinfo/firewall-wizards |

You should verify if the ports are allowed either in implied or explicit rules. (try to enable the logs on the implied rules for a short time to get some logs about the auth). I recommend to use explicit rules and allow only from explicit sources. I agree it's better if the daemon accepts connections only on internal IPs, but for this you have to ask checkpoint how to do. > thanks > > Frank > _______________________________________________ > firewall-wizards mailing list > firewall-wizards@... > https://listserv.icsalabs.com/mailman/listinfo/firewall-wizards > > _______________________________________________ firewall-wizards mailing list firewall-wizards@... https://listserv.icsalabs.com/mailman/listinfo/firewall-wizards |

I have looked at the implied rules and I do have an explicit rule to
deny all and I don't see anything that would allow this connection. I even created a rule to block this and put it at the top and still don't see any changes. To answer the other emails, Yes, I'm sure I could put an ACL in the front router to block access, but I was hoping to find a better solution.

Frank,
The Checkpoint FW1 Gateways don't accept to apply the rule base from external interface. you can always do a fw monitor to see if it is droping or accepting the packets. cheers Jacson On Mon, Aug 24, 2009 at 13:21, Francois Yang<francois.y@...> wrote: > I have looked at the implied rules and I do have an explicit rule to > deny all and I don't see anything that would allow this connection. > I even created a rule to block this and put it at the top and still > don't see any changes. > > To answer the other emails, Yes, I'm sure I could put an ACL in the > front router to block access, but I was hoping to find a better > solution. > > Frank > >>> >>> >> >> Hi Frank, >> Even if the daemon is listening on the port, you still have to go through >> the rulebase to be able to connect. >> You should verify if the ports are allowed either in implied or explicit >> rules.

It is accepting the packets.
I can get to the page from the outside world. I don't see any logs for bad attempts. I can sit here all day and put in bad passwords.
