It looks like I've just hit the same bug. It looks like it is not related with authpf but rather with anchors generaly. I'm loading anchor from pf.conf, then this anchor loads another one with some rules. I have two similar rules in there and disabling one of them will stop returning an error from this anchor.
pass in quick log proto tcp to { 10.58.16.10 10.58.16.20 10.58.16.30 } port 1522 pass in quick log proto tcp to { 10.58.16.11 10.58.16.21 10.58.16.31 } port 1522 I have quite a bit ancors so I'm failing to load rules few anchors ahead anyway. Revelant parts of config are as follows: /etc/pf.conf: anchor "vpn1" in on $if_vpn1 load anchor vpn1 from "/etc/anchors/vpn1.conf" /etc/anchors/vpn1.conf: anchor "user4" in from 172.31.224.217 load anchor user4 from "/etc/anchors/vpn1/user4" /etc/anchors/vpn1/user4: pass in quick log proto tcp to { 10.58.16.10 10.58.16.20 10.58.16.30 } port 1522 pass in quick log proto tcp to { 10.58.16.11 10.58.16.21 10.58.16.31 } port 1522 -- View this message in context: http://openbsd-archive.7691.n7.nabble.com/authpf-error-failed-to-create-table-Device-busy-tp321195p322214.html Sent from the openbsd user - misc mailing list archive at Nabble.com.
