I believe these 127.0.0.1 loopbacks are not "true network connections" and so IPV6 traffic will not pass since you blocked IPV6 networking.

These 127.0.0.1 internal loopbacks are not "true connections" per se.

Did you actually try to pass IPV6 traffic thought that host? If you did, I would be surprised if any IPV6 traffic would pass since you have already disabled IPV6 networking via "sysctl -w net.ipv6.conf.all.disable_ipv6=1".

You might want to check to make sure when you installed your proxy server that it did not unintentionally enable your intended block / disabled setup.

PS: You should use CODE tags when you post and insure your posts are well formatted and easy for everyone to read.

SHOREWALL6-TCFILTER(5)						  [FIXME: manual]					    SHOREWALL6-TCFILTER(5)

NAME
tcfilters - shorewall6 u32 classifier rules file SYNOPSIS
/etc/shorewall6/tcfilters DESCRIPTION
Entries in this file cause packets to be classified for traffic shaping. Beginning with Shorewall 4.4.15, the file may contain entries for both IPv4 and IPv6. By default, all rules apply to IPv6 but that can be changed by inserting a line as follows: IPV4 Following entries apply to IPv4. IPV6 Following entries apply to IPv6 ALL Following entries apply to both IPv4 and IPv6. Each entry is processed twice; once for IPv4 and once for IPv6. The columns in the file are as follows (where the column name is followed by a different name in parentheses, the different name is used in the alternate specification syntax). CLASS - interface:class The name or number of an interface defined in shorewall6-tcdevices[1](5) followed by a class number defined for that interface in shorewall6-tcclasses[2](5). SOURCE - {-|address} Source of the packet. May be a host or network address. DNS names are not allowed. DEST - {-|address}} Destination of the packet. May be a host or network address. DNS names are not allowed. PROTO - {-|protocol-number|protocol-name|all} Protocol. DEST PORT (dport) - [-|port-name-or-number] Optional destination Ports. A Port name (from services(5)) or a port number; if the protocol is icmp, this column is interpreted as the destination icmp-type(s). SOURCE PORT (sport) - [-|port-name-or-number] Optional source port. TOS - [-|tos] Optional - specifies the value of the TOS field. The tos value can be any of the following: o tos-minimize-delay o tos-maximuze-throughput o tos-maximize-reliability o tos-minimize-cost o tos-normal-service o hex-number o hex-number/hex-number The hex-numbers must be exactly two digits (e.g., 0x04)x. LENGTH - [-|number] Optional. Must be a power of 2 between 32 and 8192 inclusive. Packets with a total length that is strictly less than the specified number will match the rule. EXAMPLE
Example 1: Place all 'ping' traffic on interface 1 in class 10. Note that ALL cannot be used because IPv4 ICMP and IPv6 ICMP are two different protocols. #CLASS SOURCE DEST PROTO DEST # PORT IPV4 1:10 0.0.0.0/0 0.0.0.0/0 icmp echo-request 1:10 0.0.0.0/0 0.0.0.0/0 icmp echo-reply IPV6 1:10 ::/0 ::/0 icmp6 echo-request 1:10 ::/0 ::/0 icmp6 echo-reply FILES
