From 8e0e1a99e5510c7575ab8a09145d6b4354692d55 Mon Sep 17 00:00:00 2001 From: Nicolas Fort Date: Mon, 26 Aug 2024 18:10:01 +0000 Subject: T6647: firewall. Introduce patch for accepting ARP and DHCP replies on stateful bridge firewall. This patch is needed because ARP and DHCP are marked as invalid connections. Also, add ehternet-type matcher in bridge firewall. --- data/templates/firewall/nftables.j2 | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'data') diff --git a/data/templates/firewall/nftables.j2 b/data/templates/firewall/nftables.j2 index 155b7f4d0..034328400 100755 --- a/data/templates/firewall/nftables.j2 +++ b/data/templates/firewall/nftables.j2 @@ -376,8 +376,14 @@ table bridge vyos_filter { {% if bridge.output is vyos_defined %} {% for prior, conf in bridge.output.items() %} - chain VYOS_OUTUT_{{ prior }} { + chain VYOS_OUTPUT_{{ prior }} { type filter hook output priority {{ prior }}; policy accept; +{% if global_options.apply_to_bridged_traffic is vyos_defined %} +{% if 'invalid_connections' in global_options.apply_to_bridged_traffic %} + ct state invalid udp sport 67 udp dport 68 counter accept + ct state invalid ether type arp counter accept +{% endif %} +{% endif %} {% if global_options.state_policy is vyos_defined %} jump VYOS_STATE_POLICY {% endif %} -- cgit v1.2.3
