Essentially, you'd need to have a LOT of "rebel sympathizers" in positions of authority (in system) and a way to pull off a bloodless coup off world. The objective isn't DESTRUCTION (of the "if I can't have it, no one can!" variety) but rather a STAND DOWN type of condition until tensions can ease.
Also, the LBB A1 days were when planets aside from the mainworld only existed if they were gas giants ... and Feri/Regina HAS NO GAS GIANT.
Therefore, the "only" source of (starship) fuel would have been either the starport or the lakes/oceans of Feri. This means that the cadence of operational tempo will necessarily tether the Express Network to operations local to Feri itself. If the rebel forces arrange a circumstance in which "fuel shuttles" are unable to wilderness refuel OR obtain fuel from the starport ... then the Express Network communication relay through the Feri system would be forced to Stand Down simply due to fuel starvation needed to support operations.
No need for destruction ... just a bottleneck in logistical support (fuel) would be sufficient to "cut" Feri off the Express Network ... without any shots being fired/craft damaged or destroyed. The Scout Base would still be operational, but it would be subsisting on reserves only without any local resupply.
No need for explosives ... just fuel starvation ought to suffice for this.
The anti-Imperial rebels don't even need to be overtly hostile to the IISS. Instead, it could be a circumstance of "things are Too Hot™ down here" dirtside for any unauthorized entries into atmosphere. Authorized is fine, but the "authorities" who would sign those authorizations do not have complete control of the situation under atmosphere and cannot guarantee the safety of ANY craft that wants to make a wilderness refueling touchdown on water. Tensions are simply Too High right now, so for your own safety (IISS), treat Feri as something of a No Go Zone until the boil over in tensions passes.
Basic idea here is that the situation on Feri is ... CHAOTIC ... with rebel command structures not completely in control of their own rebellion. There could be a lot of "freelancers" and mercenary situations going on out there, in which coordination with political objectives remains stuck at the "lip service" level while taking advantage of the situation. The whole political environment is a stew of tensions that has been brought to a boil ... but not a roiling boil (yet) ... and even the rebel command is trying to keep their most extreme elements from running wild (and doing stupid things that "feel good" in the moment, but which will have long lasting repercussions that no one really wants).
In other words, Feri is "flirting" with needing an Amber Zone trade classification. The situation is "right up to the line" on what it would take, without crossing over that line which would mandate an Amber Zone.
THREATENING the Scout Base there would definitely do it.
WARNING the Scout Base to "steer clear for the time being" until the circumstances on Feri itself can move in the direction of a resolution, producing a Stand Down Of Normal Operations in the Express Network ... would not necessarily (in and of itself) be enough to warrant an Amber Zone classification. Informing the Scout Base Director to "stay out of this mess, our complaints are not with YOU" in order to preserve the infrastructure, lives and resources of the Scout Base would be both a prudent move and a highly practical one on multiple fronts.
When that Stand Down condition starts "taking too long" ... re-negotiations of subsistence logistics would have to take place, so the Scout Base doesn't "starve in place" ... but if any logistical support deliveries to the Scout Base "inflame tensions" down on Feri, there's going to have to be a very complicated dance going on (either legal and/or extralegal) to keep a minimum level of subsistence supplies of logistics flowing to the Scout Base without letting such dealings become public knowledge.
And what once felt like a "reasonable and prudent precaution" in the first place turns into a New Normal™ as the conflict on Feri drags on ... with no end in sight.
The problem is that the rebels DO have a legitimate grievance against the Oberlindes Megacorporation.
The situation could potentially be resolved by "reshuffling the Imperial Nobility" responsible for Feri, which would essentially allow the rebels to "win" against their oppressors and sanction the divestiture of Oberlindes from controlling the economic fortunes of Feri (thereby, "throwing off the shackles" that have been put upon the population by corporate cronyism). This COULD be a maneuver that the Duke of Regina has in his back pocket ... but isn't willing to use until the situation on Feri develops more fully, in a "keep your powder dry" opportunistic way depending on how the rebellion plays out.
In other words, the whole thing's a MESS which NO ONE wants to take credit for creating, but there are plenty of parties who would like to take credit for ending it (even if it really isn't over yet).
"Defeat is an orphan. Victory ... has a thousand fathers."
