Hi there,

I'm hosting OPNsense 24.7.11 as a VM on ESXi 8u3 and seem to be having issues with IPv6. Currently I have my WAN configured with DHCPv4 and DHCPv6 as my FNO supported settings. My FNO does fully support IPv6 but I haven't been able to find info about the prefix. Currently I have it set to 60 and seem to be passing all IPv6 tests but I think those are just to check boxes and not for actual stability.

On my Windows PC, as long as IPv6 is enabled on my NIC (Intel I225-V) I get strange intermittent network issues. Pages will just stop loading and then load randomly, pages will load slowly, stop and then finish loading instantly. Apps like Steam, Battle.Net, Apple Music etc throw network errors and then correct themselves after a few seconds. All of this goes away when unchecking IPv6 in the NIC config.

Right now I have no idea where to begin testing for stability, does anyone know a good place for me to start?

Hi there,

I have a ESXi host with OPNsense installed serving as my router connected to an Asus RT-AC88U in AP mode.
The issue I'm having is I can connect to my GPON/ONT with WAN set in DHCP mode fine but it provisions a CG-NAT'd IP.
When I switch to PPPOE and use my PPPOE credentials that work on my Asus router (not ISP provided router) it connects fine.
But when I do the same on OPNsense I just get "connecting..." from the logs.
Strange thing is, I had OPNsense running in this exact scenario for 2 years prior, just about 4 months ago I decided to switch back to my regular router and decomission my ESXi host, I've now redeployed everything but seem to be stuck here.
Has anyone else dealt with this issue?
ISP is saying PPPOE connectivity is being rejected from their end but like I said I've gotten this to work before and it does work on my regular Asus router.

Hi there,
I'm new to community and would like to know if it's at all possible to route traffic based on port number? The VPN config is a simple PPTP tunnel.
