pptp of wl500g

[once]

Hi,everybody:
I am a newer to use wl500g.Now i have a problem:when i used PPTP to connect to a ipcop firewall,it throwout a error:No auth is possible..
I looked for the cause,then i found that:

Diagnosis: your pppd is refusing to perform MS-CHAP-V2 authentication. The PPTP Server requires it, and so it terminates the connection. The known causes are:
pppd could not find a matching entry in the chap-secrets file, (see below for causes)
pppd was built without MS-CHAP-V2 support (quite uncommon).

Then i want to know was the pptp of wl500g built with MS-CHAP-V2 support ? I checked my chap-secrets file many times,and also the redhat9 can use the file to connect to the ipcop,then why??

Who can help me?

Now my problem is resolved.This tells us the debug information can only tell you "maybe it's the cause",but maybe it's not.

After looking for a long time(about 2 days),i decided to find the way to get out of the trouble.So i guess maybe it's only because the method of authentication is not supported.So...

I refused all the anthentication listed:
refuse-eap
refuse-pap
refuse-chap
refuse-mschap

and i was not sure whether the command is the found so i added:
ip-up-script /usr/local/sbin/ip-up
ip-down-script /usr/local/sbin/ip-down
and pty '/usr/sbin/pptp 192.168.100.21 --nolaunchpppd'

also added :
user 111
password 111
connect true
to make sure the name and password are accepted.

Then the wl500g's pptp connected to the ipcop's pptpd successfully.

Maybe there is superabundance.But i hope it's userful.

After the wl500g being connected to the ipcop firewall,i want to make the two lans below the wl500g and ipcop one lan.But i cannot ping each other.Maybe a route rule should be added,but i donnot know what to add.

I have tried to add:"route add -host 192.168.4.1" but it's not effective.And so is "route add -net 192.168.4.0 netmask 255.255.255.0 dev ppp0".

Then what should i do? Please somebody come to help me..
