Hello again,
I have tried a while to get UDO transport, but I don't really
understand iptables. Could anyone see what is wrong with this, which
works for ip:
#!/bin/sh
iptables -F; iptables -t nat -F; iptables -t mangle -F
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --set-mss
1100
#Above is attempt 14/3/06 to get pptp tunnel through this working.
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -m state --state NEW -i ! ppp0 -j ACCEPT
iptables -A INPUT -p icmp -j ACCEPT
iptables -P INPUT DROP #only if the first two are succesful
iptables -A FORWARD -i ppp0 -o ppp0 -j REJECT
iptables -A FORWARD -p icmp -j ACCEPT
# Now add 62694 for the gnutella
iptables -A INPUT -p tcp --dport 62694 -j ACCEPT
iptables -A INPUT -p udp --dport 62694 -j ACCEPT
# Now add 6346 for mutella
iptables -A INPUT -p tcp --dport 6346 -j ACCEPT
# Now try samba
iptables -A INPUT -p tcp --dport 139 -j ACCEPT
iptables -A INPUT -p tcp --dport 445 -j ACCEPT
iptables -A INPUT -p udp --dport 137 -j ACCEPT
iptables -A INPUT -p udp --dport 138 -j ACCEPT
# Now for ssh
#iptables -A INPUT -p tcp --dport 22 -j ACCEPT
### Try to set up afs .. does not work
##iptables -A INPUT -p udp -m udp --dport 7000:7009 -j ACCEPT
##iptables -A INPUT -p udp -m udp --dport 750 -j ACCEPT
