Hi all,
This is the first time that I write in this forum, also if I’m an old reader of this site, so I tried to look for a similar question in other topics, but none seems to reproduce exactly my “huge” problem:
My users(1) randomly(2) begin to not be able to go to the Internet.
When this happens, an user can ping m0n0wall Lan IP and m0n0wall Wan IP (3), but He can’t ping the router IP, while m0n0wall server (or other users) can ping the router IP(4).
Please help me, because the problem is in the hotspot of a Wi-fi Civic network in a little village of South Italy!
Thanks in advantage
Best regards
Giuseppe
Optional Notes :
(1) This happens both dchp clients or users with static ip address, but sometimes not all users are involved, other times all users are disconnected. Users can be wireless or cabled connect.
(2) It seems seriously random:
2.1 there is nothing of particular in logs,
2.2 the time the user remains connected is not the same (can be hours or few minutes)
2.3 It succeeds both if the user use P2P or simply surf the web, or do nothing in internet
2.4 I checked mem, cpu usage, etc…everything seems ok
(3) Seldom neither the Lan ip or the Wan ip can be reached.
(4) M0n0wall always pings the router, and moreover the router always goes to the Internet
Other Notes:
(5)This problem doesn’t depend on:
5.1Number of users, used bandwidth, or connections number
5.2Pc Hardware (many physical/virtual machines where tested)
5.3 M0n0wall version (I used more versions)
5.4 some users are connected
(6) In order to solve my problems I reduced M0n0wall configuration:
6.1 no captive portal
6.2 only Lan default rule in firewall section
6.3 traffic shaper has only an upload rule for each user
6.4 only nat 1:1 is used, no other nat rules
6.5 dhcp server is very simple
(7) The Lan schema is simplified in the simplest schema:
M0n0wall
-------------
| WAN IP | -----> Lan Router ---> Internet
| |
users -----> | LAN IP |
