lan (192.168.0.*) wan (pptp adsl Netherlands)
about 20 - 25 vpn connections (ipsec psk md5 ) to zyxels or vigor
all works well but when m0nowall is up and running after about 5 or 6 hours the internet is getting
unstable when a ping to our dns of our ISP provider and a get a lot of time outs.
It get so unstable that we cannot work anymore.. Reboot te m0n0wall and everything is fine again.
I also tried when the Internet is unstable te reset iptables and ipsec but that doesn`t help.
