QUESTION Access bindings on the voice vlan?

[shuggans]

Hi all - Ive set up an eth0.11 interface (voice vlan is 11). Once I changed the sip and iax custom configs and restarted networking + asterisk I not cannot access the pbx through ssh or http via the native vlan, but CAN access it via the voice vlan IP.

Wondering if theres something apparent I missed, or if anyone has any ideas?

I figured this out with the help of a few people on the freenode IRC server and digging into some redhat documentation.

If anyone else runs into this issue:
edit /etc/sysctl.conf with nano or vi. look for the line:

net.ipv4.conf.default.rp_filter = 1

And change the 1 to either 0 to turn off rp filtering, or 2 to change its level to "loose".

After doing this I can now ping any of the vlan interfaces created on the physical interface from any other vlan on the network (that doesnt have ACLs in place preventing it).
