[pptp-server] New installation and network problems

[Percy E Perez]

Hello all,


I have just installed pptpd ( stable version), and something rather unusual
just happened...  My entire netwok, actually mostly workstations frozed...

I downloaded ppptpd just today, installed it under a Redhat 6.1
distribution, supplied by DELL.  When thru the redhat-howto... , read the
FAQ, got the server to work,, tested it wirh an NT Workstation 4.0, i get
connected no problem... BTW, i am not using any private IPS...

my simple conf. for testing purposes is:

/etc/pptpd.conf

debug
localip 208.203.135.254
remoteip 208.203.135.253
(i only wanted to tested first... )


/etc/ppp/options.pptp

lock
debug
auth
+chap
proxyarp

Of course i made 2 more changes:

	    echo 1 > /proc/sys/net/ipv4/ip_forward
	    echo 1 > /proc/sys/net/ipv4/conf/all/proxy_arp

that was it, it worked greatl... until an hour later... :)

just for reference:

system has 2 nics, both with 208.203.135.X numbers.

One also I noticed under my /var/adm/messages the following:

Any help would be greatly appreciated.
PS: This server also provides DNS services...
