локалка 172.16.0.0/24
Два шлюза:
172.16.0.2 (AM 2.4 + up + back , 2.4.26-std-up-alt13)
Провайдер1 отдает через ADSL ppp0

172.16.0.3 (AM 2.4 + up + back , 2.4.26-std-up-alt13)
Провайдер2 отдает через ethernet pptptunnels ppp0

Ситуация, переход с первого провайдера на второго.
на первом работал Openswan - щас благополучно работает на втором провайдере.

Когда на клиентских машинах (win XP pro SP2), меняю шлюз и DNS , с
первого провайдера
на второго:
1) броузер (IE 6 и FireFox 1.5 , работа не через прокси) не фига не
показывает.
2) клиентская машина благоволучно пингует все в инете;
3) tracert в венде идет
4) tcpdump показывает:
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
