You using DSL? It definitely sounds like an MTU problem. The default
MTU of 1500 is probably too high.
> Hi there,

> Version- monowall 1.22
> WAN - PPPoE (WADSL)
> LAN - fixed, dhcp enabled
> firewall rules: LAN and WAN pass any, any any, any...
> When first time used (factoey defaults) i had trouble conecting with
> www.!gmail.com, some blog web sites. Aslo was unable to do any POST

> My first step was swiching browsers (Firefox, IE, Opera) and some

> My second step was VPN with my office, it works perfect (i also use

> My next step was analysing monowall logs, and i notice that it blocks

> I turned on monowall again (ssh works fine, ftp works fine), problems

> I checked monowall firewall rules, so Checked "Allow fragmented
