I can't get my iptables set up correctly. It seems to work perfectly except that the loopback is being denied.
I have tried the two following configurations to no avail:
-------------------Configuration 1--------------------------
## Loop Back ##
/sbin/iptables -A INPUT -p tcp --syn -s 127.0.0.1 -j ACCEPT
######## Deny Everything else ########
/sbin/iptables -A INPUT -j DROP
-------------------Configuration 2----------------------------
## Loop Back ##
/sbin/iptables -A INPUT -i lo -j ACCEPT
######## Deny Everything else ########
/sbin/iptables -A INPUT -j DROP
Could someone please shed some light on this for me?
TIA
