squid config generator having problems with ipv6 address

[onnieoneone]

Hi,

I have ipv6 working well (I believe). I get a prefix on my opnsense host from my ISP (XS4ALL) and distribute it to downstream ipv6-only vlans using radvd.

I am trying to set up a non-transparent (opaque?) proxy in each of these vlans using the built-in squid proxy from opnsense. Here I have a problem.

I set the proxy to use the ipv6-only vlan interface as a "Proxy interface" but the squid.conf doesn't get generated correctly. I get:

Code: [Select]

# grep -E 'https_port|http_port' /usr/local/etc/squid/squid.conf
http_port 127.0.0.1:3128 intercept
http_port [::1]:3128 intercept
http_port 192.168.1.10:3128 
http_port 10.1.8.1:3128 
http_port 10.1.9.1:3128 
http_port 10.1.6.1:3128 
http_port 10.1.2.1:3128 
http_port 10.1.4.1:3128
http_port :3128   <--- problem line
http_port 10.1.5.1:3128 
You'll see some other ipv4-only vlan interface addresses there.

My ipv6-only vlan interface looks like this:

Code: [Select]

# ifconfig lagg0_vlan640
lagg0_vlan640: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
ether 00:02:b0:1a:68:39
inet6 2001:dead:beef:a8:202:b0ff:fe1a:6839 prefixlen 64
inet6 fe80::1:1%lagg0_vlan640 prefixlen 64 scopeid 0x14
nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
media: Ethernet autoselect
status: active
vlan: 640 vlanpcp: 0 parent interface: lagg0
groups: vlan

If I put that address in the squid.conf replacing the 'problem line' above it seems to work correctly, clients in that vlan can use the proxy just fine:

Code: [Select]

# netstat -an|grep 3128
tcp4       0      0 10.1.2.1.3128          10.1.2.23.33264        ESTABLISHED

tcp4       0      0 10.1.9.1.3128          *.*                    LISTEN
tcp4       0      0 10.1.8.1.3128          *.*                    LISTEN
tcp4       0      0 192.168.1.10.3128      *.*                    LISTEN
tcp6       0      0 ::1.3128               *.*                    LISTEN
tcp4       0      0 127.0.0.1.3128         *.*                    LISTEN

Could it be that the squid.conf generator just isn't inserting that address correctly? I use the unbound plugin too and it puts that ipv6 address in its config file just fine.

Thanks
