modified /etc/init.d/S95done
sleep 30
/etc/init.d/network restart
/usr/sbin/dropbear -s -p 443

edit firewall.user to add

iptables -t nat -A prerouting_wan -p tcp --dport 443 -j ACCEPT
iptables -A input_wan -p tcp --dport 443 -j ACCEPT

Thanks for your post. I'm trying to do the exact same thing, wgt634u, e220 and openwrt..

What openwrt version are you using?
What packages have you installed to make this work?

Thanks

I used latest build of kamikaze 7.09, though I think any build will be fine

I built with relevant support for usb components and usb serial and comgt package (which allows configuring 3g in network scripts etc.)

my post assumes some basic linux knowledge too.

I will point out that I have an e270 and e220, and both intermittantly disconnect and i need to modprobe usbserial again and restart network script (or reboot).

I am pretty convinced this is a bug in the modems firmware, as I have tried on several different linux distros and got disconnects (with different messages ) on all of them, though newer distros like heron seem to recover better.

If I was doing this again, i would get a 3g phone like the sony k800i or newer as it supports usb ethernet , i.e. you connect the usb cable and openwrt sees an ethernet, does a dhcp request and has an ip on the internet, no ppp scripting etc.
