"VPN на RedHat 7.3"

Добрый вечер!
Буду рад, если кто-нибудь мне поможет.

Очередной раз сталкиваюсь с проблемами.
Поставил pptpd-1.1.4-b4 и ppp-2.4.2-b3.
В логах вот что:
Apr 22 22:41:54 localhost pptpd[15138]: CTRL: Client 192.168.2.222 control connection started
Apr 22 22:41:54 localhost pptpd[15138]: CTRL: Starting call (launching pppd, opening GRE)

Apr 22 22:41:54 localhost pppd[15139]: Exit.
Apr 22 22:41:54 localhost /etc/hotplug/net.agent: assuming ppp0 is already up
Apr 22 22:41:54 localhost /etc/hotplug/net.agent: NET unregister event not supported

lsmod говорит вот что:
Module                  Size  Used by    Not tainted
ppp_deflate             4128   0  (autoclean)
zlib_deflate           21504   0  (autoclean) [ppp_deflate]

ppp_generic            26796   0  (autoclean) [ppp_deflate ppp_async]
slhc                    6420   0  (autoclean) [ppp_generic]

ядро - 2.4.20-28.7smp

поддержка gre-туннелей в кернеле есть? если есть в виде модуля, то modprobe ip_gre. Если не помогает - смотреть в сторону firewall
