Okay, Openvpn stopped working. I tethered to my cell phone while out and about (which uses a GPRS). I tried using my vpn through it and it wouldn't work. In fact when I got to a wifi spot it wouldn't work there either. It hasn't worked all afternoon. Did I break it? Do I have to redo all the vpn setting? I will try reloading all the settings.
For the future, in theory is it supposed be able to work through GPRS?

After trying so many different things, it seems as though the VPN is sort of working. I am not sure what is going on. So When I login to my vpn Jaiku works but Twitter fails to load(both are block normally) via Mauku. But I can't go to Twitter's website either via Tear. So it is kind of working because I can go to Jaiku.
Here is my current configuration:

client
dev tun
proto udp
remote openvpn.ivacy.com 1194
resolv-retry infinite
nobind
persist-key
persist-tun
ca ivacy-keys/ivacy-ca.crt
cert ivacy-keys/ivacy-client.crt
key ivacy-keys/ivacy-client.key
tls-auth ivacy-keys/ivacy-tls.key 1
ns-cert-type server
comp-lzo
verb 3
auth-user-pass
redirect-gateway
script-security 3
reneg-sec 0
redirect-gateway def1

ca ivacy-ca.crt
cert ivacy-client.crt
key ivacy-client.key
tls-auth ivacy-tls.ke

Let me know if I did something wrong of could have done better.
And here is my current test log:

ca ivacy-ca.crt

I see some double entries. I've made them fat. Comment entries you do not wish to use out by putting a # before them, or simply remove the entries you do not wish to use. Remove the first redirect-gateway so def1 stays. Don't know about your ca/cert/key/tls-auth entries. The last tls-auth entry is incomplete. Perhaps your paste is incomplete though.

Can you post your /etc/resolv.conf after OpenVPN client is running and got the DNS servers pushed? It seems only 1 DNS server is pushed by the OpenVPN server. In any case, I'd remove any Chinese DNS servers, but without OpenVPN client running you may have to readd them.

After OpenVPN client runs, can you try to ping (may require root access) www.twitter.com and see if it resolves, and you get replies?

One problem with OpenVPN may be that it quickly gets a timeout and goes poof. This doesn't combine well with GPRS. Maybe don't abuse the connection with too much bandwidth, and use a caching HTTP proxy which serves low quality JPEG. Also keep in mind your N8x0 is using cryptography _and_ a browser. It eats resources.

Sidenote: Using range 1.0.0.0/8 for private networking is currently not allowed. I don't understand why they do that... oh well.

thanks for your help allnameswereout,
okay I took out the repeats on the config and still same issue Jaiku but no twitter.
How do I remove chinese DNS ...I have Openvpn running? Then what? also how do I ping twitter? Don't I need their IP address to send a ping? Will a domain name work?

And yes, the incomplete line was my copy job.

Instructions are incomplete see post below!!!

After changes you must re-import your OpenVPN client config again with the OpenVPN applet.

To remove Chinese DNS servers one normally edits /etc/resolv.conf and put # before all nameserver entries _except_ the ones pushed by OpenVPN server. According to your log that is 1.254.2.2 and 1.254.2.3

However because Maemo uses resolvconf together with dnsmasq you should make sure OpenVPN client works together with resolvconf because else resolvconf overwrites /etc/resolv.conf the whole time! To work together with resolvconf make sure OpenVPN client is shutdown and then add in your OpenVPN client config the following:

Code:
up /etc/openvpn/update-resolv-conf
down /etc/openvpn/update-resolv-conf

foreign_option_1='dhcp-option DNS 1.254.2.2'
foreign_option_2='dhcp-option DNS 1.254.2.3'
foreign_option_3='dhcp-option DOMAIN vpn'
And, again you must re-import your OpenVPN client config again with the OpenVPN applet.

To test DNS, fire up OpenVPN client then
$ host -v -t a www.twitter.com

On bottom it should say

Received ? bytes from 1.254.2.2#53 in ? ms where ? are variable numbers, what matters is the IP address listed. It should be either 1.254.2.2 or 1.254.2.3

To ping

$ rootsh
# ping www.twitter.com

Ping command resolves www.twitter.com to an IP address. That is, assuming the DNS servers work and allow you to resolve it. If Twitter is blocked by Great Firewall of China, you can assume the DNS servers block resolving domains from Twitter as well. Also, the DNS requests are tunneled and therefore come from your VPN endpoint, not from within China. For one, this looks suspicious and leaves trace. Second, some ISPs only allow DNS access from clients within their network.

So I copied resolv.conf and moved it so I can open it and just see (since I don't know how to open it within XTerm), and all it says is "nameserver 127.0.0.1". It doesn't list a bunch of different ones. Should I change it to list 1.254.2.2 and 1.254.2.3?

No, because it will be overwritten by resolvconf the whole time. It lists 127.0.0.1 because you're running dnsmasq.

This is why you must use /sbin/resolvconf which is utilized by the script /etc/openvpn/update-resolv-conf

In your OpenVPN client config add

Code:
up /etc/openvpn/update-resolv-conf
down /etc/openvpn/update-resolv-conf
and script-security value from whatever it is to

Code:
script-security 2
Don't worry, this is because you're going to execute external script.

If you don't have update-resolv-conf then here is a copy of mine

Code:
#!/bin/bash
# 
# Parses DHCP options from openvpn to update resolv.conf
# To use set as 'up' and 'down' script in your openvpn *.conf:
# up /etc/openvpn/update-resolv-conf
# down /etc/openvpn/update-resolv-conf
#
# Used snippets of resolvconf script by Thomas Hood <jdthood@yahoo.co.uk> 
# and Chris Hanson
# Licensed under the GNU GPL.  See /usr/share/common-licenses/GPL. 
#
# 05/2006 chlauber@bnc.ch
# 
# Example envs set from openvpn:
# foreign_option_1='dhcp-option DNS 193.43.27.132'
# foreign_option_2='dhcp-option DNS 193.43.27.133'
# foreign_option_3='dhcp-option DOMAIN be.bnc.ch'

[ -x /sbin/resolvconf ] || exit 0

case $script_type in

up)
	for optionname in ${!foreign_option_*} ; do
		option="${!optionname}"
		echo $option
		part1=$(echo "$option" | cut -d " " -f 1)
		if [ "$part1" == "dhcp-option" ] ; then
			part2=$(echo "$option" | cut -d " " -f 2)
			part3=$(echo "$option" | cut -d " " -f 3)
			if [ "$part2" == "DNS" ] ; then
				IF_DNS_NAMESERVERS="$IF_DNS_NAMESERVERS $part3"
			fi
			if [ "$part2" == "DOMAIN" ] ; then
				IF_DNS_SEARCH="$part3"
			fi
		fi
	done
	R=""
	if [ "$IF_DNS_SEARCH" ] ; then
        	R="${R}search $IF_DNS_SEARCH
"
	fi
	for NS in $IF_DNS_NAMESERVERS ; do
        	R="${R}nameserver $NS
"
	done
	echo -n "$R" | /sbin/resolvconf -a "${dev}.inet"
	;;
down)
	/sbin/resolvconf -d "${dev}.inet"
	;;
esac
Save it to /etc/openvpn/update-resolv-conf
And to make it executable by root # chmod 755 /etc/openvpn/update-resolv-conf

Really sucks I don't have a N8x0 to test...

..but it works for me. My /etc/resolv.conf becomes

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 194.109.6.66
nameserver 194.109.9.99
