No internet connection

[arnaudvdv]

Hi everyone,

I dont have Internet connection with the following setup:

I have a Firebox 700 setup in the following manner:
Routed mode
External IP aa.bb.cc.14
Gateway IP aa.bb.cc.13 (this is my Internetmodem no NAT)
Internal IP 192.168.2.1

NAT is configured to use 192.168.2.0/24

From a workstation I can ping trusted interface and I can ping External interface (aa.bb.cc.14) but I cant ping aa.bb.cc.13 (modem).

In the log I get denied packets from the Internetmodem (aa.bb.cc.13) to aa.bb.cc.19) on port 520.

This works fine with a WatchGuard SOHO but cant get it to work with a Firebox III 700.

Anybody an idea??

I forgot: my router IP aa.bb.cc.13 also shows up in automatically blocked sites list, so I put its ip in Blocked Sites Exceptions.

Thx in advance

can you take a look and see if you have a dynamic NAT entry for trusted-external. Also you do have rules for outgoing ping, dns, http configured

 

[arnaudvdv]

Yes, I have an entry for trusted-external. Further it is a standard setup. I made the ping-service log everything (allowed and disallowed, incoming and outgoing). When I ping the modem (aa.bb.cc.13), I do get an allowed outgoing logentry but no denied incoming.

Thx for responding.

are you able to ping anything else on the net such as your ISP DNS servers etc?

 

[arnaudvdv]

No, I cant get through the firewall, from the trusted side (LAN) the furthest I get is pinging the External interface of the Firebox.

you seem to have the correct setup the only other thing that I can think is to change the external interface on the firebox to be 10MBps and full duplex as opposed to auto. this is under network...configuration...NIC configuration I have had issues with it being auto in the past. if this does not work run the inital setup again and see if this makes a difference
