[Ayuda] problemas con IPMASQUERADE

Lun Dic 17 18:48:04 CST 2001

que tal amigos de foro, le escribo para saber si
alguien me puede echar la mano con mi configuraciòn de
IPMASQURADE, cambie de version 6.1 a 7.1 de RED HAT y
ya no jala, bajè la nueva versiòn de ipmasquerade para
el kernel 2.4, pero tampoco ha jalado y me saca unos
errores (que meustro al final), què puedo hacer para
que jale o bien conocen algun proxy server para linux?

Errores: 

[root en server /root]# /etc/rc.d/rc.firewall-2.4
