│ You need at least one DNS IP address to resolve the │

│ addresses of useable servers when the connection is │
│ established. Would you like to add these addresses │

wo yes



│ │
│ Many providers have routers that do not support TCP packets with │
│ a MSS higher than 1460. Usually, outgoing packets have this MSS │
│ when they go through one real Ethernet link with the default MTU │
│ size (1500). Unfortunately, if you are forwarding packets from │
│ other hosts (i.e. doing masquerading) the MSS may be increased │
│ depending on the packet size and the route to the client hosts, │
│ so your client machines won't be able to connect to some sites. │
│ There is a solution: the maximum MSS can be limited by pppoe. │
│ You can find more details about this issue in the pppoe │
│ documentation. │
│ │
│ Should pppoe clamp MSS at 1452 bytes? │
│ │
│ If unsure, say yes. │
│ │
│ (If you still get problems described above, try setting to 1412 │
