Re: Routing trouble with PPPoE on 3.8
2006/6/16, Srikant Tangirala [EMAIL PROTECTED]: I am trying to connect my obsd 3.8-stable system to internet via PPPoE ( ISDN connection-64Kbps). ppp program reports an established connection, ifconfig shows an IP address assigned to tun0 interface. But i simply can't use any program like ping, ftp or firefox to connect to any server. They say no route to host. I must be doing something stupid. Is the pf ruleset the problem? Probably not. ppp(8) is your friend. default: set log Phase Chat LCP IPCP CCP tun command pppoe: set device !/usr/sbin/pppoe -i rl0 set mtu max 1492 set mru max 1492 set speed sync disable acfcomp protocomp deny acfcomp set authname [EMAIL PROTECTED] set authkey set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0 add! default HISADDR This should give you a default route(8).

Routing trouble with PPPoE on 3.8
Hello
I am trying to connect my obsd 3.8-stable system to internet
via PPPoE ( ISDN connection-64Kbps). ppp program reports
an established connection, ifconfig shows an IP address
assigned to tun0 interface. But i simply can't use any program
like ping, ftp or firefox to connect to any server. They say
no route to host. I must be doing something stupid. Is the
pf ruleset the problem?
I have configured the userland pppoe with a plain ppp.conf:
default:
set log Phase Chat LCP IPCP CCP tun command
pppoe:
set device !/usr/sbin/pppoe -i rl0
set mtu max 1492
set mru max 1492
set speed sync
disable acfcomp protocomp
deny acfcomp
set authname [EMAIL PROTECTED]
set authkey
When i run ppp, here is what i see-
#ifconfig rl0 up
#ppp pppoe
Working in interactive mode
Using interface tun0:
ppp ON mycomp dial
ppp ON mycomp Warning: deflink: Reducing configured MRU
from 1500 to 1492
Ppp ON mycomp
PPp ON mycomp
PPP ON mycomp
$ifconfig
lo0: flags=8049UP,LOOPBACK,RUNNING,MULTICAST mtu 33224

scopeid 0x6
#cat pf.conf
scrub in all
block in all
block out all
antispoof quick for { rl0 tun0 lo0 }
pass in log on tun0 proto tcp from any to any port ssh flags S/SA \
synproxy state
pass out on tun0 proto tcp all modulate state flags S/SA
pass out on tun0 proto { icmp, udp } all keep state
pass in log on rl0 proto tcp from any to any port ssh flags S/SA \
synproxy state
pass out on rl0 proto tcp all modulate state flags S/SA
pass out on rl0 proto { icmp, udp } all keep state
Do i need to have the above three rules for both tun0 and rl0?
pf is enabled in rc.conf apart from inetd and sshd. Not running
named.
This is a simple home PC- i386 with GENERIC kernel patched
up to date. rl0 is definitely the right interface, got it from dmesg
output. Sorry, did not include dmesg output since it is too long
to type. If needed, i will.
I did not customize dhclient.conf. I created a hostname.tun0 with
just dhcp in it. That did not solve my problem. Still cannot connect.
I do not have any other hostname.rl0 etc.No other config files in
/etc/ppp directory were changed.
I did not customize resolv.conf by hand. Seems like ppp puts
stuff in it everytime i invoke it.
#cat resolv.conf
nameserver 203.197.30.4
nameserver 202.54.2.17
Kindly let me know what i'm doing wrong.
Thanks a lot for your time.
Srikant.

Hello, make sure your not mixing man pppoe(4) and pppoe(8) together.
Hope this will help you verify that this is not a problem.
